How much does penetration testing cost in 2026?

We live in the age of AI-assisted hacks, frequent data breaches and consumer protection regulations such as GDPR and PCI DSS. Penetration testing has become an essential security requirement for businesses of all sizes, rather than just banks and governments. 

Faced with the task of getting a penetration test done, the sheer number of providers can be daunting. How do you know if they’re any good? Can you tell what level of security expertise was delivered by reading the report? Was your application secure, or did the tester simply not find the serious weaknesses?

We walk through the questions to ask upfront, what drives the cost of a pentest, and how AI pentesting changes the equation.

How much does penetration testing cost?

People often ask what the cost of a standard penetration test is. Unfortunately, due to the variety in size and complexity of IT systems, this is like asking how long is a piece of string. It depends what you are working with, and how much depth you need to go to. If you imagine it like painting a bridge, it depends how big your bridge is, and how many coats of paint you want - just a thin covering might leave you exposed to the elements.

What is the average cost of a penetration test?

Pen tests are usually quoted on a 'day-rate' basis. Very broadly, you can expect to pay anything in the range of $1,500-$2,500 per day, or £1,200-£2,000 per day in the UK.  

Day rates vary from vendor to vendor based on things like reputation, certifications, and special requirements for the tester’s experience, although discounts can be negotiated if you’re buying lots of days (anything more than fifteen days would be considered a large test).

Day rates are typically flat, or tiered based on the seniority of the consultant carrying out the test. The more complex your requirements, the higher the day rate, as a more senior and experienced security consultant will be needed.

Does the type of penetration test affect the cost?

You might be wondering if a particular type of pen test costs more than another, such as a network pen test, or an application pen test. As previously mentioned, penetration testing companies charge based on day rates, rather than charging for different types of tests. So regardless of what you are testing, the cost will come down to the scope and number of days required to complete the assessment.

How does scope affect the cost of a pen test?

The scope of a penetration test is determined by various factors, such as the number of pages and features within a web application, how easy it is to access the systems, or the level of assurance needed.

To establish the scope, the vendor will often need to get a demo of your product, or gather information about your environment. As a rule of thumb, the less questions they ask at this stage, the less likely you are to get an accurately quoted piece of work.

The scope will determine how many days will be required to complete the assessment, as well as the seniority of the consultant required to give the assurance requested. Both of these factors will affect the price.

For example, the cost of a web application penetration test could range from $4,500 - $37,500.This is because a small, non-complex web app test carried out by a junior tester could take 3 days, at a day rate of $1,500 ($4,500 in total). On the other hand, a large, complex web app test carried out by a senior tester could take 15 days, charged at a higher day rate of $2,500 ($37,500 in total).

There’s also no standard when it comes to scoping a piece of work, so you might find estimates differ. One organization may scope a job as 3 days work, and another as 5, depending on their viewpoint. These are their best estimates, it’s hard to tell for sure until you’re doing the work exactly how long it will take.

Some manual pentesting firms do offer fixed-fee tests, but going back to the bridge analogy, if they're quoting a fixed price without asking how big the bridge is, you should probably be worried about coverage.

As with anything in life, the price you are quoted should reflect the quality that your penetration test will be delivered at - but in an industry where the quality of a test is hard to judge, there are bound to be some rogue traders out there. Take care to ask the right questions and don’t skip the due diligence process before deciding on a provider.

What affects the quality of a pentest?

The quality of a penetration test comes down to two things: certifications and experience.

On certifications, look for testers with respected qualifications like OffSec’s OSCE(3), PNPT, or SANS 542/560/588. In the UK, CREST is one of the most recognized certification bodies for penetration testing.

One thing to watch out for: a company can be a "CREST member company" without every individual tester being CREST-certified. Always ask about the person who'll actually be doing the work, not just the company badge. Their credentials matter just as much as the firm's.

That said, certifications can't cover everything. There's no exam for every type of technology out there, and that's where experience fills the gap. A tester who's seen a wide range of environments is more likely to spot issues across different tech stacks. Where possible, check your provider has hands-on experience with the technologies you're running. If they don't, a good tester can get up to speed, but it might take longer, which can affect the price.

With manual pentesting, the quality of your test depends on who's available, what they've seen before, and whether their certifications match your stack. AI pentesting removes that variability, giving you a consistent skill and experience level every time. 

How much does AI pentesting cost?

AI pentesting has changed the pricing model for penetration testing. An AI web app pentest launches in minutes, returns results in hours, and can cost a fraction of a manual engagement. There's no waiting weeks for a tester to become available, no scoping calls, and no consultant day rates.

How does the cost of AI pentesting compare to manual pentesting?

Where manual pentesting is priced on consultant day rates (typically $1,500-$2,500/day), AI pentesting has shifted to two common models: a flat fixed price per test, or a "right-sized" price where the scoping phase takes the size and complexity of your application into account and quotes for a given level of coverage. Fixed-price tests tend to range from $4,000 to $8,000, while right-sized pricing varies more widely depending on the application. For example, Intruder's AI pentests start from $4,000, or $3,500 for existing customers. For a fuller comparison of what different tools charge, see our AI pentesting tools roundup.

Either way, compared to the $4,500-$37,500 range for a manual web app pentest, the cost is significantly more predictable.

From $4,000 per AI pentest, running a test quarterly or after every major release becomes realistic. Most organizations test annually because that's all they can afford with manual engagements. AI pentesting makes it possible to test more often without the cost scaling in the same way, which means fewer gaps between when code ships and when it's actually been tested.
