Built by IT people,
for IT people
THSApps is a suite of monitoring tools built by Permission Email Ltd, a UK-based software company focused on giving IT teams and MSPs the visibility they need.
Our story
We started building monitoring tools because we were frustrated by the same problems our customers face - silent failures, unexpected changes, and the constant anxiety of not knowing what is happening across a sprawling IT estate.
Each THSApps product was born from a real pain point. DriftWatch started because a DNS change took down a client's email for hours before anyone noticed. IntuneSentry came from the nightmare of managing Intune policies across dozens of tenants with no way to track drift. DMARCWatch, AlertWatch, and SPScan followed the same pattern: real problems, solved with purpose-built tools.
Every product shares the same design language, the same alerting infrastructure, and the same team management. Learn one, and you know them all.
What we believe
Visibility over complexity
Monitoring tools should surface problems clearly, not add another layer of complexity to your day.
Real-time matters
Finding out about a DNS hijack 24 hours later is useless. Every THSApps product is built for speed.
Built for teams
IT is a team sport. Every product supports teams, permissions, and multi-channel alerting out of the box.
