A few years ago, cybersecurity felt like a big-business problem.
Not anymore.
Most attacks we respond to now start with something small - a remote employee’s unpatched laptop, or an old remote-access tool left open.

With Windows 11 becoming increasingly locked down, the company’s clear shift towards recurring revenue through Microsoft 365, Copilot, and other cloud-based services, it’s fair to ask.
