What is Penetration Testing?

Penetration Testing

Penetration testing (or pen testing) is a vital tool that businesses can use to ensure their data remains safe and secure against a wide variety of cyber threats. The process essentially consists of running a simulated attack on your current cyber defences and identifying where any weaknesses may be. Once these weak points have been identified it becomes much easier to develop a highly effective cybersecurity strategy.

Pen testing acts as an incredibly efficient way to identify these weaknesses as many businesses and business networks have never previously suffered an attack. It is only in the aftermath of such an attack (or simulated attack) that these issues become clear.

Penetration testing differs slightly from a vulnerability assessment in that there is a simulation (or ‘ethical hack’) that takes place. When carrying out vulnerability tests, you are merely getting an overview of systems in place and potential areas of risk. When used in conjunction with one another, penetration testing and vulnerability testing are powerful tools against any potential threat.

Benefits of Penetration Testing

The benefits of pen testing are there for all to see. In the modern age, businesses simply cannot afford to be reactive to cyber threats. Doing so costs companies around the world millions each year. As well as being a proactive approach, there are various other benefits associated with penetration testing.

Be Proactive

As we mentioned, by assessing the risks your network faces you are taking a proactive approach to cyber threats. It is much easier to keep malware out of a system than it is to get rid of it once infected.

Helps to Identify Specific Areas of Weakness

Pen testing generates very specific and accurate reports. Employing experts to ‘hack’ a network using the same techniques and reacting to the same elements as malicious hackers would, a clear and accurate picture is painted.

Produces a Clear Plan of Action

Once the testing has been completed a full report is compiled, complete with actionable steps to prevent malicious attacks. We can support you through the process of implementing these points to ensure network wide compliance and overall security.

When Should I be Pen Testing?

Conducting penetration testing is always a good idea. That being said, there are some key periods when businesses can particularly benefit and when conducting testing is slightly less disruptive.

Changing IT Infrastructure

If your company is already planning changes to its IT infrastructure, pen testing is the perfect tool for identifying alterations that need to be made to security. It is also useful to conduct another test once the changes have been made to assess their effectiveness.

When Launching New Products or Services

When launching new products or services your business may be exposed to new threats that you have not prepared for or even considered previously. Carrying out pen testing is a great way to mitigate these.

In the Event of a Business Merger or Acquisition

When substantial change happens to a business, such as going through a merger or acquisition, new threats can become apparent. This may be due to an infrastructure overhaul or website migration.

Checking Compliance with the Appropriate Security Measures

If you’re running an audit of your current security measures, then penetration testing is another element you should consider. Simulating hacker activity provides incredibly useful insight that is otherwise difficult to obtain.

Bidding for Large Commercial Contracts

It goes without saying that if your company is involved in bidding for large contracts then you become an attractive prospect to malicious hackers. Make sure you’re protected against the worst outcomes by ensuring your security measures are up to scratch.

Using or Creating Custom Web Applications

If your organisation uses or builds custom applications, then you need to ensure they are not a point of weakness. Particularly with new applications, it is important to conduct security analysis that includes pen testing.

Understanding Windows 10 Extended Security Updates (ESU) - what your business needs to know in 2026

As of 14 October 2025, Microsoft officially ended free security updates for Windows 10. Organisations that continue operating Windows 10 devices today - in 2026 - are now doing so in a post‑support environment, relying either on paid Extended Security Updates (ESU) or accepting increasing cyber risk. Windows updates are the backbone of endpoint security, identifying new vulnerabilities and closing them before attackers exploit them. Since the end of support deadline passed, unpatched vulnerabilities accumulate quickly, creating growing exposure across any estate still running Windows 10. Continuing with Windows 10 in 2026 can lead to: Higher cyber‑attack risk, particularly ransomware Compliance issues (Cyber Essentials, ISO 27001, GDPR, FCA/financial sector requirements) Reduced software compatibility with modern applications and security tools Increased helpdesk overhead due to outdated hardware and OS issues For organisations, this is no longer preparation for a future deadline - it’s about reducing risk now and completing the transition to a modern, supported operating system. Your organisation’s options in 2026 Businesses now have three strategic pathways depending on their hardware, budget cycle, and deployment readiness. 1. Upgrade existing compatible devices to Windows 11 If your current hardware meets Microsoft’s requirements, upgrading remains the fastest and most cost‑effective way to move away from Windows 10 ESU dependency. Benefits include: Ongoing security updates Modern protection (TPM 2.0, enhanced kernel security, improved identity protection) Support for AI‑powered features and future Microsoft roadmaps Lower risk and long‑term stability If your business has Windows 10 machines still capable of upgrading, this should be the first route explored. 2. Refresh your estate with Windows 11‑ready devices Many Windows 10 machines still in use in 2026 are now five to eight years old, and often: Fall below modern security standards Cause productivity bottlenecks Increase support tickets Consume disproportionate IT resources A structured hardware refresh offers: Predictable lifecycle management Improved reliability and performance Standardisation across departments Compatibility with modern security and MDM tooling Wavenet supports staged refresh programmes aligned with fiscal planning, ensuring minimal business disruption. 3. Continue using Windows 10 with Extended Security Updates (ESU) Microsoft’s Windows 10 ESU programme is still available, but it is: Paid per device, per year Increasing in cost each year (designed to encourage migration) Security‑only - no features or performance improvements A temporary safety net, not a long‑term strategy ESU is most appropriate when: Line‑of‑business applications are not yet Windows 11 certified You need additional time for a phased rollout Budget cycles are delaying upgrades or refresh Remote / operational environments require longer transition periods Most organisations still using ESU in 2026 should plan to exit it within the next 12–24 months. Assessing your Windows 11 readiness in 2026 At this stage, businesses need more than a simple device‑level compatibility check. A comprehensive analysis includes: Hardware readiness across the estate Application and vendor compatibility Driver and firmware validation Intune / MDM alignment Security baselines and policy impacts User profile and data considerations Deployment sequencing and pilot planning Wavenet offers full readiness assessments to provide a clear view of which devices can be upgraded, which require replacement, and where ESU may remain temporarily necessary. Why 2026 is a critical year for migration With the end of support now behind us, delaying migration further increases: Security exposure Operational risk Compliance penalties ESU costs End‑user frustration from aging hardware A well‑structured migration programme delivers: A secure, modernised endpoint environment Lower long‑term support cost Improved employee experience Better alignment with Microsoft’s cloud and security roadmap Many organisations are now accelerating migration to remove the remaining Windows 10 footprint entirely. How Wavenet supports your Windows 11 journey Wavenet provides end‑to‑end Windows 11 migration services, including: Estate discovery & readiness assessment Hardware lifecycle planning and procurement Application compatibility testing Managed upgrade or Autopilot deployment Configuration, security baselines, and Intune alignment ESU planning (where absolutely necessary) Phased rollouts with minimal disruption Whether you’re upgrading compatible devices, refreshing your estate, or transitioning off ESU entirely, Wavenet ensures a smooth, secure, and controlled migration.
