Our first product

Pulse

Pulse turns the yes-or-no answers on a cyber insurance application into verified evidence, read directly from Microsoft 365. Its first module, MFA Analysis, is live: the MFA analysis insurers ask for after a breach, run before it. One report, framed for MSPs, brokers, underwriters and the organizations themselves.

Why “Perimity”

Perimeter plus infinity.

I spent years as a senior firewall engineer and architect. Back then the perimeter was a line you could point to. It has been moving ever since.

  1. Shift 01

    The firewall

    One line drawn around the network, with everything worth protecting behind it.

  2. Shift 02

    The user

    Work left the building, and identity became something attackers could walk right through.

  3. Shift 03

    The policy

    Once attackers are inside, they go looking for the cyber insurance policy itself, because knowing a company's coverage tells them how much to demand.

  4. Shift 04

    Everything

    AI is multiplying the interfaces a company has to defend faster than anyone can count them.

The perimeter isn't a line anymore. It's effectively infinite, and it never stops changing. Perimity exists because insurance still has to price that risk, and it can't do it from a once-a-year questionnaire.
