In today’s digital landscape, cyberattacks are relentless, sophisticated, and increasingly costly. Yet, many government regulations designed to protect sensitive data and critical infrastructure fall short, not because they lack good intentions, but because they fail to explicitly require penetration testing as a standard practice. This regulatory ambiguity…
Every IT manager knows the drill. You schedule your annual penetration test, the security team arrives, runs their tools, and delivers a comprehensive report detailing vulnerabilities and recommendations. You check the compliance box, file the report, and get back to your daily grind. Fast…
When a major brand like Victoria’s Secret, MGM, or T-Mobile gets hacked, it’s all over the news. These companies are household names, and a breach affecting them often exposes millions of customer records, making it a national, or even global, story. But what about small…
Choosing a penetration tester isn’t just about credentials or price; it’s about trust, depth, and the results they deliver. In today’s rapidly evolving cybersecurity landscape, selecting the right penetration testing partner is more critical than ever. At MainNerve, we’ve witnessed significant shifts in the…
Cybersecurity threats in 2025 are evolving faster than most organizations can keep pace with. In early 2025, a global financial institution paid out a staggering $75 million following a ransomware attack. The cause? A single, compromised endpoint tied to a legacy application that had gone…
Targeted retesting focuses only on the vulnerabilities you’ve already remediated. It’s scoped tightly around the affected systems, configurations, or application components that were updated, patched, or re-engineered in response to findings from the original penetration test. This approach offers several key benefits: 1.…
In an era dominated by automation and AI-driven tools, it’s easy to assume that cybersecurity, like many other industries, can be handled entirely by machines. From auto-generated vulnerability scans to AI chatbots that claim to manage risk, automation is everywhere. However, when it comes to…
The March 31, 2025, deadline for PCI DSS 4.0 compliance has passed, and organizations now face a new security landscape that demands continuous attention, ongoing validation, and stronger risk-based decision-making. If your organization met the deadline, the work isn’t over. And if you didn’t?…
Ransomware attacks have become one of the most disruptive and costly cyber threats facing organizations today. With incidents targeting everything from hospitals and schools to large enterprises and critical infrastructure, no organization is immune. Cybercriminals exploit vulnerabilities in networks, applications, and human behavior to gain…
With the release of PCI DSS 4.0, penetration testing is no longer viewed as just a once-a-year checkbox item. Instead, the standard takes a dynamic, risk-based approach that aligns testing with real-world threats, changes in system environments, and evolving business operations. Rather than applying a…
Penetration testing is one of the most powerful tools in an organization’s cybersecurity arsenal. But a test is only as valuable as the action it inspires. Too often, penetration test reports are treated as one-off exercises or compliance checkboxes. The real value comes when those…
As cyber threats grow more complex and persistent, regulatory frameworks like PCI DSS 4.0 have evolved to demand more rigorous and transparent security practices. One of the key updates in PCI DSS 4.0 is the enhanced requirement for penetration testing reports, pushing organizations to go…
