Maximising Your Cybersecurity Investment

Network penetration testing costs are a critical consideration for every IT manager planning their 2026 budget. The price can vary widely depending on the size of your organisation, the scope of the test, and the expertise of the testers.pertise of the testers. 

Being budget-conscious doesn't mean buying cheap. It means buying value. Today, we’re explaining what you can expect to pay for a pentest and why.

The Cost of Ignoring Security

Before we look at the price tag of a test, we must consider the cost of not testing. 

In 2025, the global average cost of a data breach reached approximately $4.4 million USD (about £3.4m). This figure includes lost business, regulatory fines, and the massive expense of remediation. In the UK and Europe, GDPR fines can add significantly to this burden, costing up to €20 million or 4% of the company’s global turnover. 

Compared to millions in damages, network penetration testing costs are a fraction of the price. Investing in a comprehensive audit is effectively an insurance policy against catastrophic financial loss.

Average Network Pentest Price Ranges for 2026

While precise quotes require a consultation, industry data gives us a ballpark. 

Because the cybersecurity market is global, pricing is often discussed in USD, but UK/EU rates are comparable (typically converting £1 ≈ about $1.30 depending on market rates).

• Small Businesses: Basic network tests typically range from $5,000 to $15,000 (£4k - £12k approx).
• Mid-Sized Companies: Comprehensive assessments often fall between $15,000 and $50,000 (£12k - £40k approx).
• Large Enterprises: Extensive engagements can easily exceed $50,000, especially for continuous or red-teaming exercises.

Hourly rates for expert testers generally sit between $150 and $300 per hour. Be wary of providers offering significantly lower rates, as they may simply be reselling automated scans.

What Influences Network Penetration Testing Costs?

There is no 'one-size-fits-all' price because every network is different. Several factors drive the final quote.

Scope and Size

The number of IP addresses, servers, and devices significantly impacts the price. A small office network is cheaper to test than a multinational enterprise infrastructure.

Complexity

Testing a 'flat network' (where all devices connect to one hub without segmentation) is faster than testing a segmented network with complex firewalls, multiple subnets, and legacy systems.

Methodology

'Black Box' testing (where the tester has no prior knowledge) generally takes longer and costs more due to the reconnaissance required. 

'White Box' testing (where full access is given) is often more efficient but requires a more in depth analysis.

Compliance

If you need testing for specific standards like PCI DSS, ISO 27001, or GDPR validation, the reporting requirements are stricter, often increasing the cost.

Hidden Costs: Manual vs. Automated

A major factor often overlooked is the quality of the test. Some vendors offer very low network penetration testing costs by running automated software and handing you the printout.

That's a false economy, and it's a costly one. Automated tools catch known vulnerabilities and misconfigurations well enough. Yet, they can't understand how your application behaves, so they miss business logic flaws and chained attacks. A scanner won't notice that your checkout page lets someone edit the price field. A tester will.

There’s also a hidden labour cost. Automated scanners throw up plenty of false positives, and every one still needs a developer to check it. That's paid engineering time spent chasing dead ends, while the vulnerabilities that put you at real risk go unnoticed.

At 7ASecurity, we focus on manual penetration testing. We simulate real attackers to find the 'unknown unknowns'. 

A cheap, automated report doesn't save you money. It delays the cost and raises the stakes. Skip proper testing, and a missed vulnerability can turn into the breach. That's real money, not a hypothetical.

How 7ASecurity Maximises Your Budget

Our values include transparent pricing and long-term value. Here is how we help you manage your network pentesting costs.

• Tailored Scoping. We don’t force you into a package. We work with you to build a scope that fits your specific risks and budget.
  
• Clear Reporting. We provide actionable reports that help your developers fix issues faster, saving you internal labour costs.
  
• Free Fix Verification. Many firms charge you extra to check if you fixed the bugs they found. We offer free fix verification to confirm your remediation was successful.

Budgeting Tips for Your Next Audit

1. Define Your Goal. Are you testing for compliance or security? Knowing this helps avoid 'scope creep'.
   
2. Prepare Your Environment. Having up-to-date documentation and backups can speed up the testing process, potentially lowering costs.
   
3. Book Early. Last-minute 'emergency' testing often comes with a premium.
   
4. Prioritise Assets. If your budget is tight, focus on your most critical external-facing assets first.

Frequently Asked Questions

Why is there such a big difference in quotes? 

The difference usually comes down to 'automated vs. manual.' A cheap quote often means a tool-run scan, while a higher quote involves expert human engineers spending days manually probing your network.

Does the cost include re-testing?

Not always. Many vendors charge extra for re-testing. However, 7ASecurity includes free fix verification to ensure your vulnerabilities are truly resolved.

Is internal testing cheaper than external?

Internal security testing can sometimes be more expensive because the scope is often larger (more devices) and requires deeper access than just the external perimeter.

Can I just use a vulnerability scanner? 

A scanner is good for maintenance, but it’s not a penetration test. It can’t simulate a real hacker or find logic flaws. Relying only on scanners leaves you at risk.

Investing in Peace of Mind

Ultimately, the price of a network pentest is an investment in your company's longevity. The price of a test is predictable. The cost of a cyberattack isn’t.

By choosing a partner like 7ASecurity, you ensure that every cent spent goes toward genuine, expert-driven protection. We help you find the critical issues before the bad guys do, without blowing your budget.
