Is 2026 the end of the annual pen-test?

The Obsolescence of “Point-in-Time” Security

Pen testing helps you identify vulnerabilities in your infrastructure and applications before attackers can exploit them and gain access to your systems. But how can you prevent such attacks by relying solely on a pentest that:

• Is scheduled once a year.
• Provides only a static view.
• Fails to reveal how an attacker operates once inside.
• Doesn’t offer deeper insights that expose real attack paths and hidden connections?

And, how can you answer the actual pressing board’s question, “What would happen in the event that someone managed to get inside my business?”

With thousands of new vulnerabilities reported annually – over 48,000 in 2025 alone, many of which can be weaponised in less than a day, it’s evident that conventional pen testing practices are no longer effective.

Because in today’s dynamic landscape, attackers don’t wait, and neither should you. It doesn’t matter if your business passed the test. What’s crucial is if it’s exposed, right now.

If your business is still clinging to such outdated methodologies, now is the time to leave those practices behind and move on.

The answer is to transform the way you approach offensive security through continuous validation. Research by Gartner confirms the effectiveness of this strategy, showing that businesses that have prioritised continuous threat management and threat-led, evidence‑driven risk insights have achieved a two-thirds reduction in breaches compared to their peers.

So, take control, reduce your risk exposure, and improve prioritisation while enhancing your vulnerability management posture.

Why Annual Pen Testing Alone is No Longer Enough

Traditional pen testing was designed for a static era dominated by on-premise servers, where environments were relatively stable. Back then, once a year, a security team or external consultants would run a series of simulated attacks and manual tests.

The team would deliver a comprehensive report including a list of flaws and recommendations, and the business would tackle the issues highlighted. That was enough to feel safe. For decades, this method was the gold standard of cyber security.

But the game has changed. In today’s fast-paced environment, where hybrid cloud infrastructure, rapidly deployed APIs and ever-changing threat vectors are the norm, passing a pen-test doesn’t make your business secure any longer.

For instance, the moment you receive your pentest report, everything has already changed, from your environment to the threats and tools used by attackers. The report doesn’t show you what the hackers might do in your environment, nor can it provide prioritised remediation activities linked to potential impact and risks.

Additionally, traditional pen testing:

1. Increases your window of exposure. A single isolated event can render your defences obsolete in an instant. Imagine a critical vulnerability is disclosed the day after your annual pen-test concludes. Your business remains at risk until the next test, giving the hackers 364 days to exploit the weakness. That represents a substantial risk given that, on average, in 2025, the U.S. Cybersecurity and Infrastructure Security Agency (CISA) added 130 flaws per day to its Continuous Vulnerabilities and Exposures (CVEs) database.
2. Leaves blind spots that will remain unaddressed. Annual pen tests are time-bound and follow specific parameters. While testers may delve into certain issues, others fall through the cracks, remaining unaddressed until the next cycle. Time constraints hinder a thorough analysis and testing of every available technique, leading to a failure to understand the broader picture. As a result, subtle threats that could have the greatest impact on your business go unnoticed.
3. Lacks of real-time threat management. Pen testing helps you reach compliance with regulatory requirements. However, the goal of cyber security extends beyond merely complying with regulations, such as the Payment Card Data Security Standard (PCI-DSS) or the General Data Protection Regulation (GDPR) and generating a PDF report for auditors. To survive and thrive, your business needs continuous, real-time monitoring and management of exposures. A proactive risk management strategy that traditional pen testing doesn’t have.

A Cycle of Continuous Resistance

Continuous resistance is a more sophisticated, agile approach to cyber security, ideal for today’s increasingly complex cyber infrastructure. Rather than relying on a one-off event, it establishes an iterative process that integrates seamlessly into your business operations and empowers you to:

• Prioritise the vulnerabilities that pose the most considerable risks.
• Create a clear and actionable security plan that is easy to understand and follow.

Acora’s Cyber Incident Baseline and Readiness process, for example, includes four critical stages:

1. Auditing and scoping your business’s critical types of assets and gaps
   Every effective cyber security strategy begins with a strong foundation: understanding your attack surface. A cyber risk assessment (CRA) gives you a detailed view of your actual exposures and potential entry points from an attacker’s perspective. This allows you to predict their movements should they gain access, before the threat escalates.
2. Test assets in scope and their exposures
   Through active Directory and cloud security assessments, we go beyond CVEs by including legacy Active Directory risks, cloud supply chain risks, and configuration issues. Mapping potential attack paths and leveraging dynamic analysis techniques allows us to assess the security of newly deployed assets in real-time.
3. Provide a prioritisation list of identified critical exposures
   Cut through the noise of endless vulnerabilities and stop trying to fix every single flaw. Through offensive tests and red teaming, we leverage the assessed data and step into the shoes of attackers. That allows us to generate a 10-item to-do list and prioritise them accordingly to help you focus on what truly matters. We rank weaknesses based on risk, business impact, and whether they are actively being exploited. This risk-based approach enables you to allocate resources efficiently and implement the correct defensive measures that make a real difference.
4. Build an end-to-end baseline of your estate
   In this final stage, we create a clear list of priorities, risks, and actions. This is fundamental for helping you focus on outcomes that are impact-led and data-driven, while ensuring compliance. By doing so, you can directly tackle the high risks your business is facing and improve your cyber security posture.

The Reality of Risk & The Surge in Baseline Assessments

Stricter regulations and recent high-profile data breaches have served as a wake-up call for businesses of all sizes. Leaders are quickly realising that their:

• Lack of centralised visibility across networks and applications,
• Insufficient knowledge regarding lateral movement, and
• Inability to prioritise risks based on impact leaves them unprepared to confront the recent surge in cyber threats and data breaches.

As traditional penetration testing has proven insufficient, companies are seeking a deeper understanding of their cyber risks. Thus, data-driven threat assessments are becoming the norm, enabling organisations to identify and remediate risks more effectively.

Acora’s latest report confirms the importance of acting quickly in the face of cyber risks. It shows that businesses that adopt an evidence-based approach to risk management and shift their mindset from passive protection to proactive resilience are the ones making significant progress.

Thinking Like an Attacker

In the real world, threat actors have one goal: breach your defences. They don’t care if your security dashboard is green. Hackers constantly refine their techniques and vulnerability discovery tactics to execute increasingly sophisticated attacks.

That is why focusing solely on addressing low-risk vulnerabilities to satisfy compliance metrics can be utterly detrimental. You may overlook high-risk attack paths until it is too late.

Adopting an adversarial perspective, akin to that of a ransomware group, empowers you to stay ahead of security risks and outpace attackers with a proactive approach.

Acora’s case study “Going Beyond Traditional Penetration Tests and Thinking Like an Attacker” demonstrates that continuous improvement, validation and an accurate picture of your risk posture are paramount.

By engaging red teams, businesses continually simulate potential attack strategies similar to those employed by real hackers. Automated testing tools, artificial intelligence and machine learning algorithms allow them to detect latent flaws before any malicious actors and respond to threats in real-time.

That is how optimal security is forged: through rigorous, ongoing testing that detects vulnerabilities and actively confirms that they are effectively mitigated.

From Compliance to Mobilisation: The Operational Shift

Effectively addressing and reducing vulnerabilities requires more than identifying and fixing issues solely to meet regulatory requirements. It involves creating a culture where active defence against threats is an ongoing process and the top priority of your IT and security teams.

The Issue With the Compliance Mindset
Compliance-driven businesses tend to fix issues primarily to satisfy clients, board members, or oversight bodies. This limited approach results in a superficial understanding of their actual security posture. That’s why they often fail to address underlying issues.

The Power of the Suppression Mindset
In contrast, the suppression mindset focuses on proactively mitigating threats and preventing attacks before they happen. When you adopt this approach, your business gains broader visibility of its attack surface, enabling you to identify and address vulnerabilities quickly.

Shifting to Mobilisation: How to Transform Security from a Blocker to a Business Enabler

This shift requires a dynamic partnership between IT and security departments. To achieve it, your teams must prioritise security measures based on the real threat landscape and work together to:

• Align security measures with business objectives. Ensure that security initiatives support broader business goals. For instance, if your business focuses on innovation and scaling, seek security measures that enable such initiatives while safeguarding key assets. It will protect your business while building trust and confidence among stakeholders.
• Leverage and evidence-based. Back your security decision with solid data. Whether you are scheduling necessary downtime for patching or implementing critical configuration changes, clearly communicate the rationale behind these actions. You will foster collaboration rather than conflict.
• Evaluate current security measures and identify areas of improvement. A robust cyber security posture isn’t always about investing in the latest, shiny tools on the market. Sometimes, you can achieve the most significant improvements by simply refining existing tools and technologies. Fine-tune your current systems to maximise their capabilities. You will keep your costs down while ensuring protection from evolving threats.

Ultimately, the journey from compliance to mobilisation is about fostering a culture of security that transcends mere regulatory adherence. This bold security management strategy enables you to transform the perception of security from a blocker to a business enabler.

Moreover, this approach converts security into a vital component that actively reduces your business’s risk profile every single day, rather than once a year. When you foster collaboration and commit to continuous improvement, you outpace threats, secure your business objectives and effectively reduce risks, all at once.

Building a Dynamic Defense with Acora

Traditional pentesting is too slow to keep pace with technological advancements and modern cyber threats. Hackers are faster and smarter, and zero-day high-impact attacks are becoming more common, leaving defenders with very little time to react.

Therefore, while the annual pen test may still be a valuable tool, it isn’t enough as a standalone solution. To stay a step ahead of sophisticated attacks, businesses must embrace a security strategy that not only keeps pace with threats but anticipates them with a threat-led and evidence-driven approach that encourages continuous validation and proactive risk management.
