3 Security Stocks Tied To Rising Demand For Access Control And Monitoring

Private security has quietly become a huge business in everyday life, from late night venues to corporate offices, and investors are starting to pay attention. With US private security spending tracking above $50b in 2025 and executive protection budgets stretching higher, the stakes are rising for the companies that keep people and assets safe. This article spotlights three stocks exposed to that news trend and how each could benefit or face pressure.

The stocks covered below are just a starting sample. The full screen surfaced 39 more US listed security companies with equally grounded business cases and different mixes of guarding, monitoring, and corporate protection exposure that are not covered here. To go deeper on this theme, analyze and filter the broader universe quickly with the Private Security and Security Technology Providers screener.

Allegion (ALLE)

Overview: Allegion is a global security company that focuses on locks, electronic access control, and related software and services for commercial, institutional, and residential buildings, placing it within the broader theme of controlled access to facilities. Its brands, including Schlage and Von Duprin, equip schools, hospitals, offices, and homes with hardware, connected devices, and ongoing maintenance that align with the private security and access-control theme.

Operations: Allegion generates most of its revenue in Allegion Americas at about US$3.4b, with Allegion International contributing roughly US$921m.

Market Cap: US$13.2b

Investors looking at the private security theme may find Allegion interesting because it sells the locks, wireless access points, and software that many guards and executive protection teams use, and demand for these systems is supported by corporate security budgets and regulations for public venues. The company is emphasizing electronic and software based access control, with products such as the Schlage XE360 RealSync series and acquisitions in digital credentials and SaaS, which can support recurring revenue and margins. Allegion also carries meaningful debt and has seen recent insider selling, and its international and traditional mechanical businesses face competitive and execution risk. That combination of profitability, cash generation, and identifiable risks may make Allegion a security stock that some investors consider researching further.

Allegion’s push into software based access control could be masking a much bigger shift in how this security stock is valued. Walk through the DCF valuation analysis for Allegion and see what the market might be missing.

Satellogic (SATL)

Overview: Satellogic operates its own earth observation satellites and sells high resolution imagery, data and monitoring services that governments and large enterprises can use for surveillance, border and infrastructure monitoring and other security focused applications. The company designs and builds satellites in house, then offers geospatial data, constellation as a service and sovereign satellite systems. These offerings tie directly into rising demand for continuous security monitoring from defense and intelligence customers.

Operations: Satellogic currently reports US$31.9 million in revenue from building satellite constellations, supported by geographic exposure led by Europe at US$12.2 million and the Asia Pacific region at US$5.4 million.

Market Cap: US$712 million

Investors watching the private security theme may see Satellogic as a way to tap into growing demand for persistent intelligence rather than physical guarding. The company is leaning into defense and sovereign customers through projects like the Merlin constellation, which is designed for daily one meter monitoring, and partnerships with SynMax and SpaceKnow that target maritime tracking and critical infrastructure watchlists. At the same time, Satellogic remains loss making, has relied on equity funding and carries a high P/S multiple, so the narrative depends on whether its backlog and reported pipeline eventually support a self funded business. For investors willing to accept that trade off, Satellogic provides exposure to security focused satellite data as this part of the market evolves.

Satellogic’s push into sovereign satellite constellations and defense monitoring could be masking a much bigger story around security driven demand. Get the full picture in the 2 key rewards and 2 important warning signs (1 is major!)

APi Group (APG)

Overview: APi Group is a global fire, life safety and security services company that designs, installs, inspects, services and monitors systems like sprinklers, alarms, electronic security and elevators for commercial, institutional and critical infrastructure customers. That focus on installed and monitored safety and security infrastructure is what links APi Group directly to the private security theme in this screener.

Operations: APi Group generates most of its revenue from Safety Services at about US$5.7b, with Specialty Services contributing roughly US$2.7b and revenue led by the United States at about US$5.6b.

Market Cap: US$17.0b

APi Group sits at the practical end of the private security theme, installing and maintaining the fire, alarm and electronic security systems that regulators and insurers increasingly expect in offices, hospitals and critical infrastructure. One area of potential appeal for investors is the emphasis on inspection, service and monitoring work that is often tied to statutory safety requirements, which can support recurring revenue and more predictable cash flow. This is backed by a sizeable order book and active bolt on acquisitions in fire, safety and elevator services. Balancing this are factors such as reliance on external borrowing, integration risk as deals accumulate and ongoing pressure from labor and input costs. Those cross currents make APi Group a company that some investors may consider examining more closely when assessing long term security infrastructure demand.

APi Group’s recurring safety and security work could be masking a much bigger story around long term infrastructure demand. For a complete overview, see the 3 key rewards and 1 important warning sign
