The importance of the security of the Department of Defense’s (DoD’s) networks is no secret (well, of course a lot of it is secret!). This is evidenced by the Department’s IT/cybersecurity budget request that annually tops $40 billion dollars. Last year’s IT and Cyberspace Activities Budget Overview perhaps said it best.

Understanding how data flows across your network is a must for effective network management. But with network perimeters becoming more dynamic than ever before and nodes spread across the cloud, home offices, and corporate data centers, gaining the visibility you need is a challenge. There are plenty of network traffic monitor software options available that can help you address these challenges, but how do you know which is best for you?

The Internet of Things (IoT) has quickly become a huge part of how people live, communicate and do business. All kinds of everyday things make up this network – fridges, kettles, light switches – you name it. If it’s connected to WiFi, it’s part of the Internet of Things. IoT raises significant challenges that could stand in your way of fully realizing its potential benefits.

When a site is down, Oh Dear sends a notification every hour. Since last year, our notifications can be snoozed for a fixed amount of time (5 minutes, 1 hour, 4 hours, one day). In the evenings and weekends, you might not want to receive repeated notifications. That's why we've added a nice human touch: all notifications can now be snoozed until the start of the next workday. You can choose this new options in the snooze settings of a check.

Getting visibility into your application is crucial when running your code in production. What do we mean by visibility?

Metrics give you information about the performance of each of the elements of your infrastructure.

Successful businesses don’t sort data — they shape it. Discover, Sentry’s query builder, gives form to your event data so you can measure performance and trace issues across all your projects. Here’s how.

We are living in a time where a difference of a mere couple of seconds can make you lose your business to another company with a faster, more easily accessible web application. In such a highly competitive space, it is important to squeeze out the maximum amount of performance from your application’s software stack and hardware infrastructure.

I’ve been an open source fan and user for many, many years, going back to before we defined the term “open source” and we called it “free software.” Whenever and wherever possible I prefer to have control over the software I run on my devices. Case in point: My internet router runs OpenWrt, which is a free/open source Linux operating system designed to replace the software provided by the router’s manufacturer.
