Application Control
Allow-list which applications can run on company devices so unknown or malicious software simply cannot execute.
Only approved and trusted software should ever run in your business
Application control decides which software is allowed to open on your computers and servers. Anything unknown or unapproved simply cannot run, so risky installers, dodgy macros and malicious scripts are blocked before they cause harm.
- Stops unauthorised or unknown apps running on staff devices
- Cuts ransomware, malware and shadow-IT risk at the source
- Gives you tighter, auditable control over what is in use
- An approved software list built from your real estate
- Documented exceptions with an owner and a review date
- Policy reviewed regularly and evidenced for audits
Do you actually know which applications are allowed to run across your business?
Ask us to review your application control and risky software usage.
Understanding application control
Most ransomware and malware attacks succeed because a user runs something they shouldn't - a dodgy installer, a macro-laden document, an unsigned script. Application control flips the default: instead of blocking the bad stuff after it appears, we only allow software you've explicitly approved. It's one of the highest-impact controls in the NCSC and ASD Essential Eight guidance, and it materially reduces what a phishing email or stolen credential can do.

How this applies to organisations like yours
Recent situations we've worked through with UK businesses - find the one closest to yours.
Situation. Partners worried that a partner clicking a fake HMRC invoice could drop ransomware mid tax season.
Outcome. Allow-listed the practice management, Office and tax tools only; unknown installers silently blocked, partners keep working.
Situation. Clinicians need to install legitimate clinical add-ins quickly without holding local admin rights.
Outcome. Just-in-time elevation lets approved add-ins install in seconds while everything else is denied by policy.
Situation. Shopfloor laptops kept getting cryptominers from USB sticks used by maintenance engineers.
Outcome. Application control blocks anything outside the approved engineering toolchain; USB-borne malware can't execute.
Situation. Audit demand for proof that no unauthorised software is running on devices holding client data.
Outcome. Audit report exported from the console in minutes - clean evidence for Lexcel and ISO 27001 assessors.
