Access Control: Why You Should Choose OSDP Over Wiegand

When upgrading or retrofitting a security system, it’s crucial to consider the best available technology. For years, Wiegand has been the go-to for access control systems, but it has significant vulnerabilities that make it less suitable for today’s security needs. Enter OSDP (Open Supervised Device Protocol), a modern alternative that offers enhanced security, greater flexibility, and more efficient system management. Here’s why we recommend OSDP as the top choice for access control.

1. Enhanced Security

Wiegand technology, which emerged in the early 1980s, has become outdated and vulnerable to attacks. Ethical hackers like Babak Javadi of The Core Group have demonstrated how quickly a Wiegand card reader connection can be hacked, making it easy for unauthorized individuals to access or deny entry to facilities and even clone credentials. OSDP, on the other hand, provides robust security features that protect against such vulnerabilities.

Javadi emphasizes, “Wiegand is not just old, it’s incredibly insecure.” This stark reality highlights the necessity for a more secure protocol like OSDP, which offers supervised communication and encrypted data transfer, significantly reducing the risk of hacking.

2. Interoperability

One of the standout features of OSDP is its interoperability. Unlike Wiegand, which has limited compatibility with newer technologies, OSDP supports a wide range of devices and systems. This flexibility allows for a smoother integration with existing security infrastructure and future-proofing as new technologies emerge.

3. Improved Functionality

OSDP’s multi-drop capabilities mean that one length of 2-conductor cable can accommodate multiple readers, eliminating the need to run individual wires for each reader. This not only simplifies installation but also reduces costs and increases system efficiency. Additionally, OSDP supports advanced features such as bi-directional communication, which allows for real-time monitoring and management of access control devices.

4. Cost-Effective Migration

Transitioning to a new standard might seem daunting, but with OSDP, the process is straightforward and cost-effective. Using OSDP converters, you can gradually migrate your system without needing to replace the entire access control setup at once. This phased approach minimizes disruption and spreads out the investment over time.

5. Proximity Card Readers and Mobile Access

Proximity card readers remain a popular choice for commercial spaces due to their convenience and contactless operation. When selecting a proximity reader system, it’s important to ensure it supports various credential types, including mobile access. Openpath, for example, offers encrypted DESFire EV2 access cards alongside mobile credentials, providing a flexible and secure solution. Openpath’s Smart Readers are also backwards compatible with many legacy access cards, eliminating the need to issue new cards to your entire organization.
