"Our CISO bought their product and used their product, and ultimately, as we started using it, we fell in love with the technology," WatchGuard CEO Joe Smolarski said, explaining why his company acquired Perimeters.
WatchGuard's acquisition of Perimeters and leadership moves
WatchGuard announced the purchase of Wilmington, Delaware–based Perimeters, a cloud application security startup founded in 2022. Perimeters employs 30 people and has not disclosed any outside funding. Yaniv Hen, who led Perimeters since its inception and previously spent nearly six years overseeing product and technology partnerships at autonomous AI provider Cortica, will lead the cloud detection and response business inside WatchGuard. WatchGuard framed the purchase as a way to bring Perimeters' technology to its partner and customer base; Smolarski said the company wanted to offer the capability to "our 25,000 partners and million businesses worldwide that we're supporting," and that WatchGuard had first become familiar with Perimeters as a customer.
What Perimeters' platform does: identity, posture and shadow IT in one
According to WatchGuard, Perimeters differentiates itself by combining identity threat detection, cloud posture management and shadow IT discovery into a single, unified platform — rather than delivering each capability as a separate point product. The platform reportedly supports more than 40 SaaS integrations, and new integrations can often be completed in only a few days. WatchGuard cited Perimeters' embedded AI capabilities as strategically aligned with the future direction of cybersecurity operations.
Integration plan: a 60-day roadmap and CloudDR alignment
WatchGuard outlined a focused, 60-day integration roadmap with key priorities including event correlation, alert deduplication, and integrating cloud detection telemetry into managed detection and response (MDR) services. Smolarski described the intention to correlate telemetry across cloud security, endpoint protection, firewall activity and MDR so that only the most important threats are surfaced. He pointed to WatchGuard's existing reach — "over a million companies using WatchGuard to protect their firms" and deployed agents plus network traffic flowing through its firewalls — as providing a deep perspective for CloudDR that, the company said, few rivals possess.
Cloud environments, identity-based attacks, and the operational stress on IT teams
WatchGuard characterized cloud environments as one of the most significant attack surfaces organizations now face because of broad adoption of SaaS platforms, cloud collaboration tools and distributed work. Smolarski said attackers are increasingly targeting cloud ecosystems because they provide direct access to sensitive business data and operational systems, and he warned that identity-based attacks are among the fastest-growing threat categories. In WatchGuard's telling, attackers commonly compromise low-level employee accounts and then pivot deeper into cloud systems to access financial data, SharePoint environments or customer records.
WatchGuard also highlighted operational drivers behind the acquisition: IT teams are increasingly overwhelmed by cloud complexity and often lack the time or visibility to continuously audit configurations. The company pointed to exposed cloud resources, improperly configured applications and abandoned services as sources of security gaps, and noted unsanctioned applications can create hidden vulnerabilities that increase organizational exposure.
What this means for WatchGuard partners, security teams, and enterprises
- WatchGuard partners: The company intends to make Perimeters' technology available through its channel footprint — Smolarski described an ambition to scale the platform across "25,000 partners and million businesses worldwide" that WatchGuard supports.
- Security and operations teams: WatchGuard is promising to reduce alert fatigue by correlating telemetry across cloud, endpoint, firewall and MDR systems, with specific near-term work on alert deduplication and event correlation.
- Enterprises and procurement leaders: WatchGuard positioned CloudDR — the cloud detection and response capability built around Perimeters' technology — as both an operational protection and a revenue opportunity, saying "CloudDR can be right there at the top from a revenue generation for WatchGuard, because the need is there" and calling the need "urgent" for customers and partners.
WatchGuard's acquisition folds a compact, engineer-heavy startup into a larger managed security footprint and sets a short, concrete timetable for technical alignment. The deal brings a platform that WatchGuard executives say unifies identity detection, posture management and shadow IT visibility into WatchGuard's operational context — and places a premium on faster integrations, AI-enabled telemetry and alert reduction. Whether that combination measurably reduces exposure in complex cloud estates will be revealed as WatchGuard implements its 60-day roadmap and rolls Perimeters technology across its installed base.
