Top Physical Security Companies 2025
When you look at the London security landscape, there are plenty of names that come up, from global giants with endless resources to local outfits trying to carve out their space. Somewhere in between, standing out for a very different reason, is CIS Security Limited. It’s not the biggest and not the flashiest, but ask anyone in the industry who’s been around a while and you’ll hear the same thing: they’ve built their reputation the hard way, over decades, and that counts for more than a glossy sales pitch.
Physical security companies sit at the front line of protection for businesses, institutions, and public spaces. They do more than place guards at doors or cameras on walls. They create the systems that keep people safe, protect assets, and make sure operations run without unnecessary risk. In Peru, one name that has steadily built a reputation for trust and reliability is Markovations. Based in Lima, the company has grown into a partner that businesses rely on when safety cannot be left to chance.
There are security companies, and then there’s Security Reconnaissance Team. Based out of Dallas and built from the ground up over the last 20 years, SRT isn’t the type of firm that blends into the crowd. While most players in this space have shifted toward scale and automation, SRT has leaned in the opposite direction, doubling down on local knowledge, hands-on leadership, and the kind of work ethic that comes from family ownership. Their success? It’s not flashy. But it’s solid. And it’s earned.
International Protective Service, Inc., better known as IPS, is one of those companies that grew out of both necessity and experience. Headquartered in Albuquerque, New Mexico, it started back in 2006 under the leadership of Aaron T. Jones. He came from a background in law enforcement and military service, which already tells you something about the DNA of the company. He had seen what worked, what didn’t, and where private security often fell short. Instead of just observing problems or filling a checkbox role, he wanted to build a team that could actually protect people and property in real time. That distinction; protective service rather than passive security; is what IPS has built its name on.
