No one sets a higher standard: What it takes to be a high security manufacturer

In a world where cyber threats, data breaches, and industrial espionage loom large as omnipresent dangers, high security manufacturers providing physical access control systems have become key players in a nation’s ability to protect itself and its citizens.

And although government bodies around the world set performance standards for the manufacturers they collaborate with to protect against such threats, there’s a whole lot more that goes into producing high security solutions than just ticking boxes for compliance.

Beyond adherence to standards, high security manufacturers must embody a culture where security is a continuous thread woven into every aspect of operations, and the ones who can achieve that while maintaining flexibility and responsiveness make the best security partners for governments around the world.
