If 2024 was the year of the “identity attack,” 2025 was the year the perimeter officially collapsed. In the last twelve months, we witnessed a ruthless optimization of the exploit lifecycle. Attackers didn’t just find bugs; they operationalized them into automated kill chains within hours of disclosure.
The fundamental problem with compliance-focused patch management: organizations optimize for passing audits rather than actually being secure. They have policies, procedures, and documentation that auditors approve while their systems remain vulnerable to known exploits. Compliance becomes a checkbox exercise divorced from actual risk reduction.
Patching your systems is essential for three reasons. First and foremost, security—unpatched software vulnerabilities allow cybercriminals to easily penetrate your endpoints and collect sensitive information, install malware, or even paralyze your business by locking each device until a ransom is paid.
In this issue: December 2025 Patch Tuesday highlights, critical or actively exploited vulnerabilities in web browsers, Android, Cisco UCCX, Cisco Catalyst Center, Fortinet FortiWeb, Palo Alto PAN-OS, SolarWinds, React / Next.js, Grafana Enterprise, WordPress plugins, GitLab, Atlassian Confluence, SonicWall SonicOS, ASUS AiCloud routers, and more.
Learn what patch managers do, why patching matters, and how to choose a linux patch management tool, with options like Action1, SUSE Manager, ManageEngine, Automox, Tanium, and JetPatch.
The idea that systems cannot ever be taken offline for maintenance has become a common refrain in many organizations. It is usually spoken with a sense of urgency, sometimes even fear, as if a short planned pause would grind the entire company to a halt.
A zero-day exploit targets a software flaw that the vendor doesn’t know about yet. The name comes from the fact that developers have had exactly zero days to fix it. No patch exists. No security update is available. Your antivirus software isn’t looking for it because nobody knows it’s there.
An unpatched endpoint is any device connected to your network—laptop, desktop, server, mobile device—that’s missing critical security updates. It could be running outdated software, an old operating system version, or applications with known vulnerabilities that vendors have already fixed.
Most patch management audits check whether you have documentation. They verify you have policies, procedures, and regular scanning schedules. They confirm you’re generating reports.
The industry has spent decades trying to create clean distinctions. “Patches are small and targeted. Updates are comprehensive and add features.” Sounds logical. Doesn’t reflect reality.

When a group of thieves recently stole gold and jewels from the Louvre in Paris, it left the world stunned. This was the Louvre, the fortress of art and history, protected by layers of surveillance, guards, and technology worth millions. Yet a small, organized team found a forgotten weakness: an upper-floor window that wasn’t as secure as the rest.
At Action1, we’re always looking for ways to simplify endpoint management while giving end users more control in a secure way. That’s why we’re excited to share a sneak peek of our upcoming Self-Service App Portal, a feature that’s now in its final development phase and coming to general availability in early 2026.
If there have been two clear effects to come out of the last five years of information security, it’s that costs have gone up rapidly, and the budgets have not, or at least not anywhere near a commensurate rate.
The end of Windows 10 support has been an IT and security priority for a long time. But despite ample warning ant time to plan, the passing of the EOL support deadline earlier this month left millions of machines without protection.
Unofficial methods to obtain or install ESU updates are not legitimate, and more importantly, they are not reliable. They may appear to work at first, but they put the system in a precarious state where updates may be partial, corrupted, or discontinued without warning.
