IT leaders know the drill—regulators and cyber insurers demand regular network penetration testing to keep the bad guys out. But here's the thing: hackers don't wait around for compliance schedules. Most companies approach network penetration testing on a set schedule, with the most common frequency being twice a year (29%), followed by three to four times per year (23%) and once per year (20%), according to the Kaseya Cybersecurity Survey Report 2024 . Compliance-focused testing can catch vulnerabilities that exist at the exact time of testing, but it's not enough to stay ahead of attackers in a meaningful way. Why More Frequent Testing Makes Sense When companies test more often, they're not just checking a box for compliance—they're actually protecting their networks. The Kaseya survey also points out that the top drivers for network penetration testing are: Cybersecurity Control and Validation (34%) – ensuring the security controls work and vulnerabilities are minimized.

The most dangerous vulnerability you've never heard of. In the world of cybersecurity, vulnerabilities are discovered so often, and at such a high rate, that it can be very difficult to keep up with. Some vulnerabilities will start ringing alarm bells within your security tooling, while others are far more nuanced, but still pose an equally dangerous threat. Today, we want to discuss one of these more nuanced vulnerabilities as it is likely lurking in your environment waiting to be exploited: Active Directory Certificate Services vulnerabilities.  vPenTest by Vonahi Security recently implemented an attack vector specifically designed to identify and mitigate these hidden AD CS threats. But first, let's explore why AD CS vulnerabilities are so dangerous and how they work. What is Active Directory Certificate Services? Active Directory Certificate Services ("AD CS"), as defined by Microsoft is, "a Windows Server role for issuing and managing public key infrastructure (PKI) cert...

Network penetration testing plays a crucial role in protecting businesses in the ever-evolving world of cybersecurity. Yet, business leaders and IT pros have misconceptions about this process, which impacts their security posture and decision-making.  This blog acts as a quick guide on network penetration testing, explaining what it is, debunking common myths and reimagining its role in today's security landscape.  What is network penetration testing? Network penetration testing  is a proactive approach to cybersecurity in which security experts simulate cyberattacks to identify gaps in an organization's cyberdefense. The key objective of this process is to identify and rectify weaknesses before hackers can exploit them. This process is sometimes called "pentesting" or "ethical hacking."  Network pentesting checks for chinks in an organization's armor to help mitigate cyber-risks and protect against data, financial and reputational losses.  Differe...
