Cyber threats don’t wait, and neither should you. From outdated systems to invisible assets, vulnerability risks can quietly undermine your business. In this article, we share top tips to help you stay ahead of attackers, close security gaps, and build a more resilient digital environment.
1. Keep Operating Systems Up to Date
Outdated operating systems are a major security risk.
We still see many customers running devices on end-of-life platforms like Windows Server 2008, Windows Server 2012, and Windows XP within their production environments.
These systems no longer receive security patches, leaving known vulnerabilities permanently exposed. Upgrading to supported versions is one of the most effective ways to strengthen your cyber resilience.
2. Prioritise Patch Management
Even supported systems like Applications and Firewalls, are vulnerable if they’re not regularly patched.
Delays in applying critical updates can leave your environment open to exploitation.
Therefore, implementing a consistent patch management process, especially for high-risk applications and infrastructure, will help close security gaps before attackers can exploit them.
3. Reduce Attack Surface with Asset Visibility
You can’t protect what you can’t see.
Maintaining an accurate inventory of all devices, applications, and services across your environment is essential.
Regularly auditing your assets helps identify shadow IT, unmanaged endpoints, and legacy systems that may introduce unnecessary risk.
