Why Physical Security? Benefits and Use Cases
While cyber-security protects data and networks from digital threats, physical security protects everything else from threats in the physical world. While both physical and cybersecurity are crucial, they serve distinct purposes.
Cybersecurity defends against digital threats such as hacking, data breaches, and malware. Physical security, by contrast, addresses the physical threats that could lead to loss or damage. Together, these two pillars of security create a holistic approach to protecting an organization’s tangible and digital assets.
The benefits of a physical security system cannot be overstated, as it covers a wide spectrum of use cases. These systems work before, during, and after a security threat takes place. Before a security risk takes place, physical security systems can make it more difficult to enter restricted areas unnoticed. Visible cameras, security lighting, and well-placed signs can also act as active deterrence, preventing crime from happening in the first place.
During a security threat, physical security systems provide real-time monitoring, lockdown capabilities, and remote access, providing a variety of ways to monitor and respond to events from anywhere in the world.
After an incident occurs, physical security systems provide video evidence for quick and efficient review and investigation processes.
Beyond protection, physical security can also enhance operational efficiency. Integrated systems, like video-linked point-of-sale transactions or automated access control rules, can increase security while streamlining daily processes. But most of all, these systems allow business owners to feel secure knowing their properties and personnel are protected, even in their absence. This peace of mind lets them focus on what matters most: running and growing their business.
