Find and Fix Risky Firewall Rules | Reach Security Demo

A firewall rule set to allow any source to any destination can stay live for months. It cancels out the rules beneath it and lets traffic pass unchecked. That kind of drift sets off no alarm. It builds up between quarterly reviews, while small teams govern 50 or more firewalls and hundreds of rule changes a week. Reach Network Security Assurance finds these controls, shows how long each has been open, ties the finding to real exposure, and guides the fix.

Cleartext is all fun and games

One of the many interesting things we stumble across in the Black Hat NOC (Network Operations Center) is the various applications exhibiting poor security hygiene. Usually it’s something in the clear that makes us chuckle before we move on to more serious matters. Sometimes it’s something more serious that requires letting an attendee know they’re leaking sensitive information.

Why Now Is the Time to Replace Your VPN

For years, the VPN has been the default answer to remote access. It solved a problem organizations faced when employees primarily worked from offices and only occasionally connected from home. That world no longer exists. Today, employees work from everywhere. Applications run across SaaS platforms, public cloud, private cloud, and on-premises environments. Security teams are expected to provide seamless access while protecting against increasingly sophisticated attacks.

Beyond Firewalls: The Role of Physical Security in Data Protection

When we talk about data protection, we almost always focus on the digital side. We discuss firewalls, malware, phishing scams, and encryption. While these digital defenses are definitely crucial, they're only half the story. A locked digital door doesn't help if an intruder can just walk in physically and take the server. Real data security needs a strategy that goes beyond the screen and into the physical world where your data actually lives.

Why Choosing the Best VPN Still Matters for Online Privacy in 2026

This isn't about niche online communities any longer. These days it's about the actual lives of countless Americans who use banks, online retailers, video streams, and employers that do business on networks they can't fully control. As the online market in private virtual networks (known as VPNs) became so saturated it developed a glut of inflated promises, misleading claims, and outright hoaxes. Choosing The Best VPN in 2026 requires navigating a digital landscape that is in flux, yet not always entirely different.

SSH ProxyJump at Scale: Where It Breaks Down and What to Do Instead

Most engineers meet SSH ProxyJump the same way: a single bastion host stands between the public internet and a private network, and one clean -J flag replaces a clunky chain of manual hops. For small teams managing a handful of servers, it feels like a solved problem. But infrastructure grows, teams grow, and the assumptions that made ProxyJump elegant at ten servers start to strain at ten thousand. What works cleanly in a small environment often becomes a liability in a large one, and understanding why is the first step toward finding a better approach.

Beyond IP addresses: How DDI solutions power telco data center operations

There is a moment, somewhere between the third ring of a phone call connecting and the first frame of a video buffering, where an entire telco data center has already done its job. A device asked a question, Where do I belong, and what is my name here? And somewhere in a rack of servers, in less time than it takes to blink, the system gave the answer.

The EU AI Act Is Here. Is Your AI Environment Ready?

AI has moved from experimentation to operational reality. Last year saw a 50% rise in access to AI for employees, with 88% of organizations using AI in at least one business function. Competitive pressure is accelerating AI adoption. While this creates opportunity, it also creates a new level of operational risk.

Ten Black Hat NOCs and counting: Corelight sees it all

Whenever I come back from a Black Hat NOC, people always ask the same question: “So, what did you see?!” They understand how unique it is to have access to the detailed logs generated by an NDR overseeing the network traffic of a conference with thousands of attendees. There is always something to see. There are always stories that come out of the packets; those stories evolve into patterns, and the patterns offer the gift of lessons.
