Enterprises don’t struggle with whether users should have access. They struggle with how that access happens and how to secure it without creating more complexity. Employees work from managed laptops, personal devices, and third-party systems. Contractors need fast onboarding. Partners can’t install agents. Some users rely entirely on a browser. This mix isn’t temporary; it’s how modern enterprises operate.

The Department of Energy’s Office of Cybersecurity, Energy Security, and Emergency Response (CESER) has released its first five-year strategic plan, following the broader national cybersecurity strategy. It’s coming at a time when the energy cybersecurity landscape is changing quickly, in some cases faster than operators can realistically keep up.

VPNs have long been considered the backbone of secure remote access, especially as organizations shifted to distributed work environments. By encrypting data in transit, they create a secure tunnel between users and corporate systems. On the surface, this appears sufficient to protect sensitive business operations and internal resources. However, encryption alone does not guarantee security. VPNs do not verify who is accessing the network, only that the connection is valid.

CVE-2025-53521 was first disclosed by F5 in October 2025 as part of their quarterly security advisory cycle. At that point, it was classified as a denial-of-service vulnerability with a CVSS v4 score of 8.7. Many security teams logged it and moved on, reasonably treating it as a lower-priority item in an already full patch queue.

There’s a little neighborhood coffee shop I love that runs like a Swiss watch. Every night, the owner doesn’t just flip the sign to “Closed.” They run a checklist: count the till, lock the back door, log fridge temps, sanitize the espresso wand, test the alarm, and write it all down. Not because they expect trouble, but because consistency is foundational to security. The shop earns trust the boring way: by doing the right things, repeatedly, even when nobody’s watching.

A VPN, or virtual private network, encrypts your internet traffic and routes it through a server in a location you choose. Your ISP, network operator, and the websites you visit see that server's IP address, not yours. That single mechanism covers every VPN use case: keeping your browsing history from your internet provider, securing a connection on public Wi-Fi, accessing a company network remotely, and reducing location-based tracking.

In a world where technology, threats, and business priorities evolve constantly, the real challenge is not predicting the future, but choosing an architecture that can adapt to it.

What began as reports about Anthropic’s Mythos model has now moved into a gated research preview called Mythos Preview. For cybersecurity, that immediately raises an important question: what happens when advanced AI can accelerate offensive workflows such as vulnerability analysis, exploit development, and attack planning? In a recent Cato blog post, we addressed the broader strategic shift this represents.
