Built support for 40+ SaaS application integrations as a young company, indicating rapid product expansion.
Small team; operational scale beyond the MSP-focused product is unproven publicly.
WatchGuard adopted Perimeters as a customer before acquiring it in May 2026, a strong real-world validation signal.
Multi-tenant, MSP-first SaaS security architecture is a meaningful design differentiation versus single-tenant CASB tools.
WatchGuard's own pre-acquisition customer use is a real signal, though no independent third-party testing was found.
MSP-delivered SaaS security is a growing need as SMBs consolidate more business data into cloud applications.
Why CISOs Should Care
Perimeters.io gives MSPs continuous visibility, built-in detection, and automated response across 40+ SaaS applications (Microsoft 365, Salesforce, Google Workspace, Jira, and more) from a single multi-tenant platform.
What Makes It Different
Purpose-built for MSP multi-tenant operations rather than single-tenant enterprise SaaS security, with WatchGuard becoming a customer before acquiring it.
The Matrix Verdict
45/100 — EMERGING / UNRANKED
