Reviewing Penetration Test Pricing In 2025: A Practical Guide for UK and EU Buyers

Penetration testing costs in the UK and EU can range from a few thousand pounds to well over £20,000. At a glance, many of these tests look the same. So why the price gap?

In 2025, pricing models haven’t changed much. Most tests are still priced per day, but the complexity of what’s being tested has changed.

The rise of custom internal tools (many “vibe coded” by non-IT or security teams), shadow IT, SaaS stacks, and cloud sprawl means that scoping a pen test properly takes more time and care.

There’s no “standard” pen test anymore.

What Does a Fair Pen Test Cost in 2025?

The most recent SECFORCE pen test pricing guide looked at pen test costs for EU and UK companies in 2025.

Based on a review of several dozen pen testing providers, the guide found that, in most cases, pen tests are priced on a per-day basis and fall into three broad daily rate price ranges.

While scopes and testing depth vary, a realistic day rate for thorough, manual testing in 2025 typically falls between £1,000 and £1,500 (or €1,200 to €1,800).

Rates below £500 per day often indicate limited testing or automated scans, while anything above £2,000/day should be justified by highly specialised scope or industry demands.

What this means is that for most buyers, the right question isn’t just "How much does a pen test cost?" it's "What am I actually paying for?”

How Penetration Test Scope Is Impacting Pricing

The biggest factor influencing a pen test quote right now is scope.

Scope is the sum of factors like:

• How many systems are being tested?
• How complex is the environment?
• What’s the risk profile?

Scope influences testing time, and testing time influences price.

For example, a basic web app might take five to six days to test properly, while a full platform with multiple environments and APIs could require several weeks.

The total price should make sense when you divide it by the proposed days and then ask what’s happening during that time. If you’re quoted 20 days for a small app, ask why. If you’re quoted five days for a critical SaaS platform, ask how they’ll cover everything in that timeframe.

In 2025 and beyond, buyers are strongly advised to make sure that whatever quote they get is based on good scoping. Larger attack surfaces mean that pen testing scope needs to be right-sized.

Reputable providers will ask detailed questions about your situation before offering a price.

If you receive a quote with no scoping call, that’s a red flag. It may be based on a fixed package or guesswork and won’t reflect your actual risk.

Equally, pricing that seems too good to be true probably is. In 2025, as in the past, low-cost pen tests often turn out to be little more than vulnerability scans repackaged as full engagements.

The Cost of NOT Pen Testing In 2025

Many organisations weigh up the cost of a penetration test but overlook the far higher cost of skipping one.

Recent ransomware statistics show that there has been a 123% increase in ransomware attacks over two years. Many of these incidents likely involved attackers exploiting vulnerabilities that would have been flagged in a penetration test.

From misconfigured permissions to exploitable logic flaws, these are the kinds of issues scanners miss, and only human-led testing finds.

In one real-world example, a layered authentication process was bypassed by chaining together minor weaknesses: username enumeration, a logic flaw that skipped the password step, and a lack of brute force protection on the final step.

A vulnerability scanner wouldn’t catch this chain, but a pen tester would.

Beyond the technical damage of a breach, there’s reputational fallout. Customers are increasingly unforgiving. The majority of consumers say they’d stop doing business with a company that suffers a major security incident.

Regulators are also tightening expectations, with frameworks like PCI-DSS and the Digital Operational Resilience Act (DORA) requiring or strongly encouraging regular testing. Even the General Data Protection Regulation (GDPR) compliance can be reinforced through penetration testing by surfacing high-risk vulnerabilities in systems handling personal data.

Pen testing is one of the few security investments that directly reduces legal risk, financial exposure, and brand damage. The cost of a multi-day engagement, often a few thousand pounds, is almost always cheaper than the aftermath of a preventable breach.

What Buyers Should Ask Pen Test Vendors In 2025

To assess whether a pen test quote is fair, ask the vendor:

• What methodology will be used?
• What systems and risks were considered in the scoping process?
• Are manual tests included, or is this primarily automated scanning?
• Can I see a sample report?
• Are there additional charges for reporting, wash-up calls, or project management?

The answers will tell you a lot more than the day rate alone.

Final Thoughts: Understanding Value Beyond the Price Tag

The difference in outcome between a checkbox pen test engagement and one that simulates real-world exploitation is significant.

A real test will go beyond finding common vulnerabilities and look at how features interact, where logical flaws exist, and how multiple weaknesses could be chained together. This kind of depth can be used to inform massive investments in security and ultimately help shape business decisions.

Cheap pen tests can create a false sense of security and do massive damage to your reputation if they overlook risks that are later exploited.
