As its name suggests, a single instance of ThreadLocal can store different values for each thread independently. Therefore, the value stored in a ThreadLocal instance is specific (local) to the current running thread.

There are exceptions, though, like InhertiableThreadLocal, which inherits parent threads’ values by default.

The latest addition to the ever growing Security Monitoring tools from RapidSpike is the ability to perform Vulnerability Scans of your external facing servers and web applications.

A couple of weeks ago we launched a new feature for Pro users: rate limiting SMS alerts. Back then we promised that free users wouldn't be left out and we've just rolled out the planned upgrade to all free accounts: we've increased the available number of monitors from 20 to 60. That's right, you can now monitor up to 60 websites completely free.
