Bugasura
Bugasura
Bugasura is our take on how modern teams should manage quality. Most test management tools still feel like they were designed in the dial-up era—slow, heavy, and full of unnecessary rituals. Bugasura cuts through all that and gives teams a clean, fast, human way to manage everything from requirements to releases. It starts with the Requirements Manager, where teams capture what needs to be built and link it directly to test cases and bugs. No scattered docs. No detective work. Then comes Test Management—reusable test cases, smart grouping, tagging, bulk actions, and fast execution. Test cycles stop feeling like paperwork. Testers stay in flow, raise bugs instantly, and don’t need five tabs open just to get work done. The Bug Tracker is where Bugasura shows its teeth. It auto-captures screenshots, logs, device info, and browser metadata—everything developers usually chase testers for. Issues come pre-loaded with context, killing the “Can you reproduce this?” loop.

Lguest
Lguest
Lguest allows you to run multiple copies of the same 32-bit kernel, simply modprobe lg, then run Documentation/lguest/lguest to create a new guest. I suggest you try this yourself, lguest is incredibly easy to get up and running. It's also quite useful: I can test-boot kernels with it in less than a second, or about 10x faster than basic qemu, and 100x faster than a real boot. And as it uses a pty as console, you can do things like pipe it through grep. lguest is all one big kernel patch, including the launcher. It's in 2.6.23-git13 and above. Lguest aims to isolate the guest so it cannot reach outside to the host (except for virtual devices supplied by the host of course), even if the guest is malicious. However, a malicious guest kernel can currently pin host memory (up to the amount of memory allowed to the guest). Most images are set up to create a console virtual consoles (/dev/tty0 etc), but the lguest console is /dev/hvc0. -

As Comodo Advanced Endpoint Protection (AEP) protects your endpoints against malware, the AEP application itself routinely comes under attack by malicious applications trying to circumvent its protection. Fortunately, Comodo AEP includes robust self-protection countermeasures that prevent malicious applications from gaining control or circumventing Comodo AEP services. AEP does this by intercepting system calls that might present a threat to the applications such as Terminate Process or Create Remote Thread are obvious examples of calls that might pose a risk to AEP. Other less obvious but actually more dangerous call would be CreateFile as it can do a lot more than just create a file. Comodo AEP intercepts these calls and only allows them to proceed if they won’t harm the Comodo process. Comodo AEP also contains a kernel mode driver that it uses to prevent attempts to modify the system kernel directly.

Tetragon
Tetragon
Tetragon is a flexible Kubernetes-aware security observability and runtime enforcement tool that applies policy and filtering directly with eBPF, allowing for reduced observation overhead, tracking of any process, and real-time enforcement of policies. eBPF enables deep observability with low-performance overhead, mitigating risks without the latency introduced by user-space processing. Tetragon extends Cilium's design by recognizing workload identities like namespace and pod metadata, surpassing traditional observability. It offers pre-defined policy libraries for rapid deployment and operational insight, reducing setup time and complexity at scale. Tetragon blocks malicious activities at the kernel level, closing the window for exploitation without succumbing to TOCTOU attack vectors. Synchronous monitoring, filtering, and enforcement are performed entirely within the kernel using eBPF.Starting Price: Free -
