Application Control & Ringfencing
Traditional antivirus is like a bouncer with a list of known troublemakers. Application control flips this: instead of trying to spot bad software, it only allows approved software to run. If ransomware isn't on the approved list, it simply can't execute - no matter how new or clever it is.
What is it?
Application control (also called application whitelisting) works on a simple principle: only software you've approved can run on your computers. Everything else is blocked by default.
Ringfencing takes this further. It draws invisible boundaries around applications, controlling what they can do even after they're allowed to run. For example, Microsoft Word can create documents, but it shouldn't be launching PowerShell commands or encrypting your entire hard drive - ringfencing stops this abuse.
This approach defeats most ransomware attacks. Even if an employee clicks a malicious email attachment, the ransomware can't run because it's not on the approved list. And even if malware somehow hijacks a legitimate application, ringfencing limits the damage it can do.
Business Benefits
Ransomware Protection
Ransomware can't encrypt your files if it can't run in the first place. Blocked by default.
Zero-Day Defence
Works against brand-new threats that antivirus hasn't seen yet. If it's not approved, it doesn't run.
Reduced Attack Surface
Staff can't accidentally install unwanted software, browser toolbars, or malware disguised as legitimate programs.
Compliance Support
Demonstrates strong security controls for Cyber Essentials, ISO 27001, and client security questionnaires.
Risks Without It
Ransomware Vulnerability
Traditional antivirus detects roughly 60-70% of ransomware. The other 30-40% can encrypt your entire business in minutes.
Shadow IT
Staff installing unapproved software creates security gaps and support headaches - you don't know what's running on your systems.
Supply Chain Attacks
Malicious code hiding inside legitimate software updates can bypass traditional security. Ringfencing limits the blast radius.
Malware Persistence
Without application control, malware can hide in startup folders and run every time a computer boots - for months without detection.
How Fresh Tech Implements This
We deploy enterprise-grade application control across all managed devices. During onboarding, the system learns what software your business legitimately uses - building your unique whitelist automatically.
Once enabled, only approved applications can run. New software requests come to us, we verify it's legitimate, and approve it within minutes. Ringfencing policies prevent even approved applications from doing things they shouldn't.
This is included in our Cyber Security services and works alongside our other protection layers to create defence in depth.
