Hire an ethical hacker with practical certifications for example CEH, OSCP, GPEN or CompTIA PenTest+.

Ensure you ask for a sample report, professional insurance, and clear testing scope. Always confirm written authorisation and ensure full post-test remediation support.

Hackers are getting smarter and stealthier. Nearly half of all data breaches now involve zero-day vulnerabilities, which evade traditional cybersecurity tools and IT monitoring.

Ethical hackers (also known as “white hats”) find those same weaknesses before criminals can exploit them.

This Guide Explains:

  • How to find the right Certified Ethical Hacker 

 

  • Which certifications matter most

 

  • What to ask before you hire

 

  • How to verify you’re working with a trustworthy partner

Why Ethical Hacking Matters

Hackers are fast becoming increasingly sophisticated, often employing zero-day techniques that can evade cybersecurity tools and IT professionals.

In fact, research shows that nearly 30% of data breaches involve previously unknown vulnerabilities.

That’s why having a certified ethical hacker (CEH) assess your systems can make the difference between prevention and disaster.

What Is Unethical Hacking?

Criminal hackers or “Black hat” hackers can break into your organisation’s systems without permission to steal data, cause disruption, or sell your sensitive information. Their motives range from financial gain to causing your business chaos just because they can.

These activities are illegal and punishable by law under the Computer Misuse Act 1990 but that doesn’t stop them.

This is where our ethical hacking services come into play. By using the same skills in a responsible way we can help to improve your business security posture by learning from the results from a test hack that does not negatively impact your business.

What Is Ethical Hacking?

Ethical hacking, or white-hat hacking, is an authorised practice of testing computer systems, networks, and/or applications to uncover any security vulnerabilities before a hacker has a chance to act and exploit your untested security gaps.

Ethical hackers use the same techniques as cybercriminals, scanning, probing, and attempting to gain access, but with one crucial difference, they do it with permission and a signed contract.

We provide this service both managed IT Support clients and non-clients to help strengthen your defences and help you close these gaps before anyone else finds them.

Should My IT Support Provider Complete My Ethical Hack?

When planning to complete an ethical hack, many businesses naturally turn to their existing IT provider. After all, your IT team already understands your systems and security setup but is that always the best approach?

The Pros of Using Your Current IT Provider for an Ethical Hack

  • Convenience: Everything happens in one place from setup to reporting.

  • Familiarity: Your provider already knows your infrastructure, reducing the time spent on onboarding and access.

  • Trust: You’re working with a team that already handles sensitive information and understands your compliance requirements.

The Cons of Using the Same Provider

  • Potential bias: When the same company responsible for maintaining your systems performs the test, there’s a risk even if unintentional of playing down any weaknesses or overlooking deeper issues.

  • Limited perspective: External ethical hackers bring a fresh, attacker-minded viewpoint that in-house teams often lack. (if using an inhouse IT team without dedicated cybersecurity experts)

  • Accountability and validation: An independent assessment provides an unbiased report the “blanket truth” you can share with management or use to verify that your IT provider is delivering the security level promised.

What Is The Best Approach To Choosing An Ethical Hacker

Many organisations choose a hybrid model with their IT provider managing remediation and ongoing security, while an independent ethical hacking team conducts the penetration test. This ensures complete transparency, objectivity, and continuous improvement of your cyber defences.

5 Reasons Your Business Needs an Ethical Hack

If your business holds sensitive data like employee details, financial information, and client records, any breach could cause reputational damage, operational downtime, and financial penalties.

By simulating real-world attacks, ethical hackers can:

  1. Detect vulnerabilities before they’re exploited

  2. Assess your resilience against modern cyberattacks

  3. Provide actionable recommendations

  4. Reduce the risk of reputational and financial damage

  5. Meet regulatory compliance (GDPR, ISO 27001, Cyber Essentials)

According to IBM’s Cost of a Data Breach Report, early detection and ethical hacking can cut breach costs by over 25%.

Can You Trust Ethical Hackers?

Absolutely, when you choose a certified ethical hacker that follow strict codes of conduct.

A Certified Ethical Hacker must do these 5 things…

  1. Seek written authorisation before testing
  2. Act honestly and within legal boundaries
  3. Protect society and client confidentiality
  4. Provide competent, diligent service
  5. Remove traces of the hack after testing

 

These ethics ensure that vulnerabilities stay private and cannot be exploited by malicious actors.

What Are The Most Vulnerable Devices to Hacking?

Any device on your network can be a target but one weak device can compromise all others.

Top 5 Common Weak Devices For Hackers

  • Smartphones
  • Webcams
  • Routers
  • Baby monitors
  • Smart home / IoT devices

With remote and hybrid work now the norm, each endpoint must be secured and regularly tested.

Real-World Examples of Successful Ethical Hacking

Automotive Cybersecurity (2015):
Ethical hackers remotely took control of a Jeep Cherokee’s steering and brakes, prompting a recall of 1.4 million vehicles and an industry-wide reassessment of vehicle cybersecurity.

 

Airport Security Testing (2019):
At Heathrow Airport, ethical hackers discovered major vulnerabilities in data storage and physical systems, leading to upgraded airport security protocols.

These examples show the value of authorised hacking in preventing catastrophic breaches.

What Certifications Should An Ethical Hacker Have?

When choosing an ethical hacker, certifications can be used to prove credibility and competence. Look for one or more of the following:

  • Certified Ethical Hacker (CEH)  EC-Council’s globally recognised credential for penetration testing and security assessment.
  • CompTIA PenTest+  Practical certification focused on hands-on penetration testing.
  • GIAC Penetration Tester (GPEN) — Validates real-world penetration testing skills.
  • Certified Information Systems Security Professional (CISSP) Advanced certification covering broader information security strategy.
  • Offensive Security Certified Professional (OSCP) A rigorous hands-on exam known for its real-world hacking challenges.

How to Vet and Hire the Right Ethical Hacker

Before hiring, confirm the following:

1. Credentials & Proof
Ask for active certifications, sample (redacted) reports, and client references.

2. Methodology
They should follow recognised standards such as OWASP, PTES, or NIST SP 800-115.

3. Insurance & Liability
Ensure they have professional indemnity insurance and provide written authorisation forms.

4. Deliverables
A professional pentest report should include:

  • Executive summary with risk ratings
  • Detailed vulnerability list and exploitation proof
  • Remediation guidance
  • Post-test validation plan

5. Communication
Ethical hackers should communicate clearly, respect your scope boundaries, and erase traces after testing.

Frequently Asked Questions

CEH focuses on theory and broad concepts where as OSCP is a hands-on, practical certification involving live exploitation in a controlled environment.

Small tests may take 2–5 days, larger corporate assessments can run several weeks depending on scope and complexity.

This timeline should be outlined within the proposal of the ethical hack.

Ask for certifications, insurance proof, sample reports, scope of work, and remediation support details.

Reputable ethical hackers carry professional indemnity and cyber liability insurance to cover testing risks.

Costs vary widely based on scope for businesses you can expect anywhere dependant on size and complexity from £2,000 for a small external test to £15,000+ for full infrastructure and web application testing.
