You allow site-specific software safely by vetting and approving each tool through application control, rather than leaving machines open. That way your engineers get the cabling-certification software, test-equipment drivers, design tools and utilities they genuinely need, while every unknown program stays blocked by default. The protection and the productivity sit together: approved tools run, unapproved ones don’t.
Security and M&E engineers use plenty of specialist software and hardware drivers, which is exactly where unvetted programs could creep in. Here’s how we keep it safe.
1. Default-deny, with quick approvals
With application allowlisting, nothing runs unless it’s approved. When an engineer needs a new tool, a quick request to us gets it reviewed and approved fast, so they’re not held up on site, and nothing unknown slips through.
2. Vetting the tool and its drivers
Specialist software often comes with hardware drivers, for example to download results from a cabling tester. We check and approve the specific installer and driver, so the kit works without opening the door to anything else.
3. Keeping site machines clean
Field laptops pick up a lot of software over time. Allowlisting keeps them to the approved set, so they stay secure and consistent, and you’re not relying on each engineer to keep their own machine tidy.
4. Managed for you
Because we manage the approved list, your engineers don’t have to think about it. New tools get approved, old ones get tidied up, and the protection stays strong without becoming a daily obstacle.
A real example: cabling-certification software approved
We support a security and M&E contractor where a site engineer needed cabling-certification software and the matching tester drivers installed to download results from a hardware tester. Because application control blocks anything unapproved, we vetted and elevated just those, so the engineer could certify on site without weakening the firm’s default-deny security.
For a security, fire or M&E contractor, this is part of managed IT and security that usually costs about £45 to £100 per user per month, scaling with your headcount, how many staff work from site, and the finance and security software you rely on.
