Outdated access control systems can lead to 43% higher risk of security breaches, 31% failure during audits, and 3x longer maintenance downtimes. If your system struggles with frequent breakdowns, integration issues, or lacks modern features like biometric authentication, it’s time to consider an upgrade.
Key Signs You Need an Upgrade:
- Frequent System Failures: Credential errors, door malfunctions, or costly repairs.
- Worn-Out Hardware: Faded keypads, corroded readers, or unreliable locks.
- No Manufacturer Support: Missing updates or hard-to-find replacement parts.
- Integration Problems: Incompatibility with modern tools like CCTV or mobile credentials.
- Security Breaches: Vulnerabilities like cloned badges or weak encryption.
- Limited Access Controls: Outdated systems lack role-based or time-specific access settings.
- Scalability Issues: Can’t handle more users or expand to new locations.
- Reliance on Physical Keys: No tracking, real-time updates, or remote deactivation.
- Missing Access Logs: No records of who accessed what, when.
- Time-Consuming Processes: Manual tasks like user provisioning and compliance reporting.

How to Upgrade Physical Access Control
1. System Failures and Downtime
Every hour of downtime creates 57 minutes of unmonitored access opportunities , with 38% of unauthorised access incidents linked to temporary fixes like propped doors during outages . These risks often arise from outdated hardware, which we’ll explore further.
Key warning signs of system breakdown include:
- Frequent credential reader errors and failed card scans
- Door lock malfunctions, especially during busy periods
- Controller communication failures that require manual reboots
For instance, a major retail chain faced more than 12 door lock failures per week, even with ongoing repairs . This recurring issue indicates a system on the verge of collapse.
"Legacy Wiegand systems lack the ability to self-correct errors, while modern solutions can automatically resolve authentication problems", says an ICT security expert .
If quarterly repair costs exceed 25% of a cloud system’s annual cost) and require three or more service calls per month, it’s time to consider a replacement.
Other red flags include monthly authentication errors exceeding 15%, controller delays longer than 2.5 seconds, or repeated battery failures during power outages.
Perhaps the most alarming issue is the "blind spots" created by outdated systems. When older access control systems can’t integrate with modern security tools, organisations are left more vulnerable to advanced threats.
2. Old or Worn-Out Hardware
Hardware failures often show up as physical wear and tear. Faded keypads, corroded card readers, and loose wiring aren’t just eyesores – they’re weak spots criminals can exploit. A striking 61% of physical breaches involve compromised hardware. For example, worn biometric scanners can mistakenly grant access, and aging magnetic locks may lose their grip.
"Legacy controllers lack the processing power to handle modern multi-factor authentication processes, especially when combining mobile credentials with facial recognition", explains a security systems analyst from Source 2.
These vulnerabilities undermine the authentication measures mentioned in Section 6. Outdated systems often face repair delays of up to 72 hours because replacement parts are no longer available. This leaves facilities exposed during critical downtime.
One hospital experienced a serious breach when worn proximity readers allowed entry via cloned badges. This case highlights how deteriorating hardware can compromise even supposedly secure checkpoints.
To minimise these risks, replace credential readers every 5-7 years and controllers every 8-10 years. Doing so can prevent a 3.4x increase in false rejections. These issues set the stage for the security breaches explored in Section 5.
3. No Technical Support Available
When manufacturers stop supporting older access control systems, it leaves organisations vulnerable to both security threats and operational disruptions. A recent study highlights that 78% of unsupported systems develop exploitable vulnerabilities within two years of losing manufacturer support.
Take this real-world example: In 2022, a Las Vegas casino experienced a major security breach due to an outdated Schlage interface. The system couldn’t receive critical encryption updates, leaving its vulnerabilities exposed because no patches or firmware updates were available.
Typically, manufacturers end support for these systems 7–10 years after installation. This creates three major challenges:
- Security Patch Gaps: Without updates, these systems become easy targets for cyberattacks. A 2023 HID Global audit found that 63% of unsupported systems had critical vulnerabilities that remained unpatched.
- Component Failures: Replacement parts for older systems are hard to find, and third-party alternatives fail 42% more often while being more expensive.
- Integration Issues: Older systems often lack the ability to implement necessary API updates. For instance, Keri Systems hardware without updated firmware cannot integrate with modern video management platforms.
The Cybersecurity & Infrastructure Security Agency (CISA) has recognised these risks. Federal facilities are required to replace unsupported systems within six months of losing support. For private organisations, experts suggest reaching out to vendors as soon as support notices are issued to discuss upgrade options.
Keeping legacy systems running after support ends is costly. Maintenance can be 300% more expensive than switching to cloud-based solutions.
To address these challenges, tools like Nedap‘s System Health Monitor can track obsolescence dates, helping organisations plan upgrades proactively. This becomes increasingly important as we dive into the difficulties of integrating outdated systems with modern security tools in the next section.
4. Cannot Connect to New Security Tools
Struggling to integrate with modern security tools adds to the risks posed by outdated systems and sets the stage for potential breaches. When older CCTV systems can’t connect to current tools, it weakens their ability to respond effectively, as discussed in the Introduction.
Many legacy systems rely on outdated protocols like RS-485, which aren’t compatible with newer IP-based security tools unless extensive modifications are made. This gap creates several issues, including:
- No automatic CCTV recording during access events
- Incompatibility with smartphone-based credentials
- Failed integration with facial recognition systems
- Disconnected IoT sensors
"The hybrid cloud approach allows organisations to maintain legacy hardware functionality during transition periods while gradually implementing modern integration capabilities", according to Avigilon’s implementation guide .
These older systems face serious technical hurdles. For instance, Avigilon’s cloud VMS requires standardised protocols that many legacy systems simply can’t support. This lack of compatibility directly contributes to the security vulnerabilities discussed in Section 5.
While partial solutions like controller upgrades or compatibility software can help, they fall short of the seamless integration offered by modern open-architecture systems. In particular, the inability to use mobile credentials limits the adoption of digital access systems – a flaw that will be explored further in Section 8.
To assess whether your system is ready for integration, focus on the speed of communication between components. A delay of more than ¼ second can compromise even basic security functions. Without meeting this performance standard, your system’s effectiveness is at risk.
5. Security Breaches
When older systems fail to work with modern tools (see Section 4), they create security weaknesses that can lead to breaches.
These risks often come from older hardware (see Section 2) that relies on outdated encryption methods. While modern systems use AES-256 encryption to secure credential data, legacy systems frequently store sensitive information with minimal safeguards.
Criminals take advantage of these vulnerabilities in various ways:
- Using inexpensive RFID writers to clone 125kHz proximity cards in seconds
- Exploiting the lack of AI-powered detection to bypass security through tailgating
Signs Your System Is at Risk
Security professionals point to several red flags that suggest your system may be vulnerable:
- Failed authentication attempts exceeding 0.5% per month
- Delays in authentication processing longer than 2 seconds
- Frequent "door forced open" alerts caused by mechanical issues
- Inability to support multi-factor authentication
Multi-factor authentication gaps are particularly concerning, as they contribute to 58% of security breaches in organisations. These encryption weaknesses also play a role in the 31% audit failure rate mentioned earlier.
For industries governed by regulations like GDPR or HIPAA, legacy systems present additional problems. Unencrypted data storage often leads to non-compliance, putting organisations at significant risk. Modern systems, by contrast, offer FIPS 140-2 validated encryption and automated tools to simplify compliance reporting.
6. Limited User Access Controls
Weak access control systems don’t just complicate operations – they open the door to the security risks mentioned in Section 5. Older systems often rely on outdated, all-or-nothing approaches, while newer solutions provide the detailed control necessary to address today’s security demands.
For example, a healthcare provider faced HIPAA violations when temporary staff retained access longer than necessary. Similarly, a manufacturer experienced intellectual property theft due to rigid vendor access policies.
Why Basic Access Systems Fall Short
Modern security needs go beyond what basic access systems can handle. Here’s how they compare:
| Feature | Basic Systems | Modern Systems |
|---|---|---|
| Access Rules | Allow/deny only | Role-based with customisable settings |
| Time Restrictions | Not supported | Adjustable access windows |
| Emergency Response | Manual processes required | Instant remote lockdown capabilities |
| Visitor Management | Permanent credentials only | Temporary, auto-expiring access options |
| Integration | Standalone systems | Syncs with HR and security platforms |
Organisations relying on outdated systems often face:
- 68% more security breaches related to privilege misuse.
- 50% slower response times to compromised credentials.
- 30% higher tailgating incidents due to missing biometric verification.
The Financial Impact of Poor Controls
One retailer saved $2M annually by adopting biometric access controls. Modern systems also support rules like: "Block warehouse access after hours unless a manager override is in place".
These gaps in access control become even riskier as operations grow, a challenge explored further in Section 7.

7. System Cannot Grow with Your Business
When your access control system can’t keep up with growth, it can lead to serious security risks and operational slowdowns. These issues not only worsen the vulnerabilities discussed in Sections 5 and 6 but also introduce new challenges.
For instance, 73% of organisations using systems older than five years can’t add biometric readers without replacing major infrastructure components.
Capacity Constraints
Older systems often have strict limitations that hinder business expansion:
| Growth Need | Legacy System Limitation | Modern System Capability |
|---|---|---|
| User Capacity | Fixed license cap (200-500 users) | Unlimited cloud-based scaling |
| Access Points | Maximum 50 doors/readers | 500+ endpoints supported |
| Response Time | Over 2-second delays at peak times | Sub-second authentication |
Hidden Costs
Retrofitting older systems can cost 58% more than replacing them outright. And even after spending more, these systems often provide 300% less capacity compared to modern cloud-based solutions.
This inability to scale also worsens the integration headaches from Section 4 and the audit challenges from Section 3.
Planning for Growth
Modern systems are designed to grow with your business. They offer:
- Modular upgrades for seamless expansion
- Cloud-based architecture with pay-as-you-grow pricing models
- Open standards (like OSDP) to replace outdated proprietary protocols
"Quarterly scalability reviews should be integrated into security strategy updates to prevent system limitations from constraining business growth", advises ICT’s technical documentation.
To avoid these issues, ensure your system has at least 50% extra capacity for users and devices. Ignoring these growth limitations often forces organisations to revert to outdated solutions like physical keys – a topic covered in the next section.
8. Still Using Keys Instead of Digital Access
Relying on physical keys in today’s world can be a major security risk. When older systems fail to keep up (as discussed in Section 7), many organisations fall back on outdated methods like physical keys. These methods often lead to serious vulnerabilities.
Here’s a real-world example: A university replaced 5,000 keyed locks with digital access and saw impressive results – lock maintenance costs dropped by 45%, and unauthorised entries decreased by 60% in just a year.
| Security Aspect | Digital Access |
|---|---|
| Lost/Stolen Credentials | Instant remote deactivation |
| Access Changes | Real-time permission updates |
| Monitoring | Detailed access logs with timestamps |
| Emergency Response | Instant facility-wide security protocols |
Why Physical Keys Fall Short
Physical keys come with serious limitations that digital systems can solve:
- No way to track who accessed specific areas or when.
- Cannot enforce time-restricted access.
- Lack of integration with modern security systems.
These shortcomings only make existing security gaps (like those mentioned in Section 5) worse.
What Digital Access Brings to the Table
Digital access systems offer a smarter, safer alternative:
- Cloud-based management for instant permission updates.
- Multi-factor authentication using cards, PINs, and biometrics.
- Seamless integration with CCTV and intrusion sensors.
- Geofencing technology, which has been shown to reduce unauthorised entries by 68%.
Meeting Compliance Standards
Modern compliance requirements often demand detailed access logs, something physical keys simply can’t provide. Digital systems, on the other hand, automatically maintain these records, helping your organisation meet compliance standards while boosting security.
In fact, organisations that switch to digital access control systems report a 30% drop in security breaches compared to those still using traditional keys.
9. No Access History Records
When digital credentials replace physical keys (see Section 8), they leave behind data trails – but only if the system is set up to record them. Without proper logging, breaches like those discussed in Section 5 can go unnoticed.
Take the 2023 warehouse theft case as an example: the investigation stalled because the system logged door openings but didn’t track user IDs. This forced the company to reissue credentials to the entire staff. Such gaps in visibility weaken both compliance efforts and operational efficiency, as highlighted in the Introduction.
| Access History Feature | Security Benefit |
|---|---|
| User Identification | Tracks who entered specific areas |
| Timestamp Logging | Records precise entry and exit times |
| Video Integration | Links access events to CCTV footage |
| Automated Alerts | Detects and flags unusual access patterns |
Modern access control systems have revolutionised security monitoring, yielding measurable improvements such as:
- 67% faster breach investigations
- 42% fewer unauthorised access incidents
Without automated logging, many organisations fall back on manual records, which have an average error rate of 38%.
Advanced Logging Features
Today’s systems go far beyond basic logging, offering features that older systems simply don’t have:
"Real-time logging with video verification, cloud-based storage with encryption, and customisable reporting filters by date, user, and access point are essential features of contemporary access control systems. Some advanced solutions even incorporate AI-driven anomaly detection to identify suspicious access patterns."
These AI-driven tools help mitigate risks like tailgating, as highlighted in earlier system analyses. By cross-referencing access logs with other security systems, organisations can create a layered defense strategy, ensuring potential breaches don’t slip through the cracks.
10. Missing Time-Saving Features
Outdated access control systems rely heavily on manual processes, creating unnecessary delays and operational headaches. These inefficiencies not only slow down workflows but also amplify the security risks discussed in Sections 5 and 9, while making scalability issues from Section 7 even worse.
| Task | Manual Time | Automated Time | Savings |
|---|---|---|---|
| User Provisioning | 2-3 hours/week | 15 minutes/week | 87% |
| Access Rights Updates | 15+ hours/week | 30 minutes/week | 96% |
| Incident Investigation | 5 hours/incident | 2 hours/incident | 60% |
| Compliance Reporting | 2 weeks | 3 days | 70% |
Modern access control systems address these inefficiencies with automated workflows that integrate seamlessly with HR platforms. For example, access permissions can update automatically during onboarding or termination, eliminating manual intervention and reducing administrative efforts by 60-75%. Additionally, cloud-based platforms reduce maintenance time by 30% using predictive diagnostics.
These advancements also align with the 67% faster breach investigation capabilities highlighted in our Introduction, making a strong case for upgrading outdated systems.
"By implementing mobile-based visitor management instead of front-desk sign-ins, we saved over 200 hours annually. The automated system handles everything from credential issuance to exit logging, freeing our security team to focus on more critical tasks."
Key Features Missing in Legacy Systems
- Cloud-based remote management dashboards
- Mobile credential deployment via email
- AI-driven alert triaging to prioritise critical threats
- Automated compliance report generation (critical for audit readiness, as noted in Section 3)
- Predictive maintenance diagnostics
Without these features, legacy systems not only fall short on efficiency but also weaken the multi-layered security approach outlined in Sections 5-9.
Old vs. New Systems Comparison
Legacy access control systems and their modern counterparts differ in three major areas:
These differences highlight why organisations facing challenges like integration failures (Section 4) and scalability limits (Section 7) often see dramatic improvements when switching to modern systems.
Modern cloud platforms tackle integration issues from Section 4 while meeting the scalability demands from Section 7. Here’s how they compare:
| Feature | Legacy Systems | Modern Solutions | Impact |
|---|---|---|---|
| Maintenance Requirements | Regular on-site visits | Remote diagnostics with 30% less downtime | Lower operational costs |
| Threat Response | Manual intervention | Automated lockdowns in under 30 seconds | 67% faster incident resolution |
| Compliance Management | Paper-based records | Automated GDPR-compliant audit trails | 70% reduction in reporting time |
Modern systems also bring advanced security features powered by AI. For instance, Amarok‘s AI-driven cameras can differentiate between everyday activities and potential threats, triggering appropriate responses automatically – no human input required.
Long-Term Value
Modern systems provide lasting benefits, including:
- Energy savings through smart building integration
- Lower insurance premiums due to better compliance reporting
- Reduced maintenance costs with predictive diagnostics
"Cloud-based access control adoption is projected to increase by 13% over the next three years, driven by organisations seeking scalable security solutions that can adapt to evolving threats."
Scalability Comparison Modern platforms are well-suited for growing businesses. Cloud-based systems allow instant scaling across multiple locations using centralised management dashboards, while legacy hardware often requires a complete overhaul to support expansion.
This comparison directly addresses the key challenges outlined in the 10 warning signs – from security gaps (Sections 5-6) to operational inefficiencies (Sections 9-10).
Next Steps
Research indicates that organisations adopting a structured approach to system upgrades experience 38% fewer security breaches after implementation.
Immediate Actions
Begin with a thorough security audit, targeting vulnerabilities such as delayed authentication (see Section 5) and missing access logs (see Section 9). According to Koorsen Fire & Security, prioritise addressing frequently malfunctioning components like door controllers and credential readers, as these directly affect daily operations. This approach tackles issues highlighted in Sections 4 (integration challenges) and 7 (scalability concerns), while leveraging the efficiency improvements discussed in Section 10.
To ensure a clear path forward, document your current system’s weaknesses in three core areas:
| Assessment Area | Key Considerations | Impact Metrics |
|---|---|---|
| Technical Integration | Compatibility with existing CCTV and alarm systems | |
| Scalability Requirements | Growth projections for access points and users | |
| Compliance Needs | Adherence to industry regulations and data standards | 70% reduction in compliance reporting time with modern systems |
Vendor Selection
When choosing a solution, prioritise vendors offering API-driven integration. These platforms allow for flexible customisation and reduce the risk of vendor lock-in.
Implementation Strategy
Roll out the upgrade in phases to maintain security continuity and ensure the system performs optimally during the transition.
Training Requirements
Allocate 8-16 hours for initial staff training, depending on the complexity of the system. Focus on:
- Real-time incident response protocols
- System health monitoring processes
Monitoring Success
Conduct quarterly security audits to compare metrics before and after the upgrade. Regularly check system health, especially at integration points with CCTV and alarm systems, to maintain top performance.
Investing in modern access control systems is a major step for any organisation. Partnering with experienced security consultants can help you find the most cost-effective upgrade strategy while meeting critical security needs.
