How to reduce security testing costs in a tech company

Yanis Grigy, CEO13 min read

You can lower security testing spend without creating blind spots or failing audits. The method: cut duplicate tests, scope deep reviews to the riskiest surfaces, and move cheap checks into the delivery pipeline. The biggest savings rarely come from buying fewer tests in the abstract. They come from removing overlap and retest churn, the places where a team pays twice for the same signal: one tool, one vendor, one audit cycle, all proving the same thing in slightly different formats.

Key takeaways

  • Costs fall fastest when you remove overlapping scans, repeated vendor work and broad pentests that ignore how much actually changed.
  • Payments, authentication, admin paths and public APIs deserve deeper testing than internal tools or low-impact services.
  • Automated gates catch cheap, repeatable issues early. Business logic abuse and chained authorization flaws still need offensive testing.
  • Retest fees shrink when remediation is tight, vendors are compared on the same scope and assurance is bought on a schedule instead of in a rush.

Cut duplicate testing before you cut coverage

Where tech companies usually overspend

The fastest savings come from removing overlap, not from trimming testing at random. The pattern is the same in SaaS, fintech and healthtech teams: one tool flags a finding, a second tool flags the same class of issue, a vendor repeats the check in another format, and someone spends hours reconciling the results. The team feels busy, but control coverage barely moves.

Tool sprawl makes it worse. When ten teams pick point solutions in isolation, you do not only buy more software, you buy more triage, more false positives and more retesting. The largest hidden line item is often engineer time, not licence fees. A scanner that costs $20,000 a year can still cost more than it saves if it creates 200 hours of cleanup and re-verification.

Automation pays when it is used well. According to IBM's Cost of a Data Breach Report 2025, security teams using AI and automation extensively shortened their breach times by 80 days and lowered their average breach costs by USD 1.9 million compared with organisations that did not. For testing, the lesson is simple: automate the repeatable work so people spend their time on judgment, not on rechecking the obvious.

Build a cost map first

Start with a 30-day inventory. List every test with its owner, frequency, trigger and compliance driver, then mark which tests catch the same class of issue. You are looking for two scanners covering the same OWASP Top 10 weakness, or an annual pentest rechecking code paths that have not changed since the last release.

That map usually reveals one of two problems: too many tools, or too many calendar-based tests with no link to change. Fix both and you stop paying for the same evidence twice. For a view of what each testing option actually costs in Europe, see what a pentest costs in Europe in 2026.

Scope testing by risk, not by org chart

What deserves deep testing

Deep testing belongs on the surfaces where a defect causes direct loss, account takeover or lateral access: payment flows, authentication, account recovery, admin panels, public APIs, tenant isolation and internet-facing infrastructure. On those paths, a single missed authorization check or injection flaw becomes a real incident.

Deep tests are expensive because they are slow, adversarial and tailored. That is exactly why they should be reserved for narrow, high-value attack paths. If your scope has 40 endpoints but only 12 can move money, change roles or expose customer data, the other 28 do not need the same treatment. Many programs make the mistake of treating every endpoint as equally interesting to an attacker.

What can move to lighter checks

Internal admin tools with limited data exposure, low-risk back-office apps and stable services with strong guardrails can usually rely on lighter checks plus periodic validation. The point is not to ignore them, it is to stop paying premium rates for surfaces that do not justify premium scrutiny.

SurfaceTypical riskRecommended depthWhy it comes first
Payment flowsHighDeep offensive testing plus targeted automationDirect revenue and fraud impact
Authentication and account recoveryHighDeep offensive testing plus abuse-case reviewTakeover paths have a wide blast radius
Public APIsHighDeep testing on sensitive endpointsEasy to abuse at scale
Internal admin toolsMediumLight testing plus scansLower exposure, narrower user base

Verdict: if you are shrinking a 40-endpoint API pentest, do not test all 40 equally. Focus on the endpoints that handle authentication, payments, secrets and privileged actions, then cover the rest with automated checks and code review.

Shift cheap checks left, keep depth for offensive testing

Automate what machines do well

The NIST Secure Software Development Framework (SP 800-218) makes the case for finding defects before release. In NIST's words, following the SSDF practices "should help software producers reduce the number of vulnerabilities in released software, reduce the potential impact of the exploitation of undetected or unaddressed vulnerabilities, and address the root causes of vulnerabilities to prevent recurrences." The practical automation set is well known: SAST, dependency scanning, secrets detection, IaC scanning, container scanning, DAST on stable environments and baseline cloud configuration checks.

The cost rule follows: every issue found before merge or in CI is cheaper than one found during a paid pentest window. You pay testers for their time either way. The difference is whether that time goes to real attack paths or to hygiene defects that could have been avoided.

Secrets are a good example. According to GitGuardian's State of Secrets Sprawl 2024, 12.8 million new secrets leaked in public GitHub commits in 2023. If you do not catch that class of issue in CI, you pay people later to investigate a problem that a pre-commit check catches in seconds.

Keep offensive testing for logic flaws

Scanners do not reliably catch business logic abuse, authorization chaining or multi-step attack paths. Those require following state across requests, roles, tenants and edge-case workflows, the way an attacker does. A payment flow that allows coupon stacking, a reset flow that leaks whether an account exists, or an admin action that only breaks after three steps will often look clean to a scanner.

The split is blunt: let tools catch repeatable defects, and spend offensive testing on the narrow paths where reasoning matters. The Verizon Data Breach Investigations Report keeps listing the human element and the exploitation of software flaws among the most frequent causes of breaches, which is another reason not to overtrust scanners.

Use compliance to narrow tests, not expand them

Map each test to a requirement

ISO 27001, SOC 2, PCI DSS, NIS2 and DORA often set testing calendars, but teams overspend when they run broad tests "for compliance" without tying them to a control, an asset or a change. If a control asks for evidence of periodic review, you do not need to retest the whole stack to prove it. You need evidence that the control works on the relevant system, at the relevant cadence, with a named owner.

Build a small matrix for each required control: accepted evidence, testing frequency, and whether automated proof is enough or manual proof is required. Compliance becomes a scoping tool instead of a blank cheque, and you have a clean answer when the auditor asks why a low-risk internal workflow did not get the same treatment as a payment API. Practical rule: if a control can be satisfied by a log, a scan result or a ticket trail, collect that first. Save human verification for the places where the standard actually demands it.

Do not let evidence work become security work

When audit evidence lives in spreadsheets, chat threads and vendor portals, security staff end up repeating the same validation in different formats. That is not stronger assurance, it is expensive duplication. Treat evidence collection as part of the delivery system: one owner, one system of record, one place that shows the fix, the test and the approval. If you have ever watched an engineer paste the same screenshot into three tools, you know the cost.

Choose the right mix of in-house and outsourced testing

What to keep internal

  • Repeatable checks, because you will run them often and tune them as the code changes.
  • Low-complexity scans, owned by the team that ships the code, because context makes triage faster.
  • Release gating, when you want failures to block merges instead of waiting for a vendor report.

Many teams buy external help for work a product team can own after two weeks of setup. A 12-person SaaS engineering team can usually run dependency scanning, secrets checks and basic DAST itself if the rules are simple and ownership is clear. What matters is not the tool, it is whether the team that wrote the code sees the failure before production does.

What to buy externally

  • Independent assurance, when you need a fresh attacker mindset and a defensible third-party view.
  • Specialist offensive testing for complex authentication, multi-tenant products and abuse-heavy flows.
  • Peak-load work, when a launch, an acquisition or a regulation creates a spike your team cannot absorb.

External testing earns its keep when the work is hard to fake internally. You are buying depth and independence, not just a report, and for a regulated product that independence makes board and customer conversations easier.

How to think about cost

  • A staff AppSec hire can replace many recurring low-complexity external scans.
  • The same hire usually cannot replace deep, specialist offensive testing.
  • A scheduled cadence with one provider usually costs less per engagement than one-off emergency work.
  • Ask vendors to price discovery, retest and reporting separately, so you only buy what you need.

Verdict: keep the steady work in-house and buy the sharp edge outside. For a 20 to 200-person tech company, that is usually the cheapest structure.

Reduce retest costs with better remediation workflows

Why retests get expensive

Poor handoffs create paid retest churn. The usual failures are unclear reproduction steps, missing severity thresholds and fixes shipped without security acceptance criteria. The tester then has to rediscover the issue before confirming the fix, so you pay for the investigation twice, sometimes three times if the patch changes the behaviour without closing the root cause.

Small process waste becomes expensive when it repeats across dozens of findings. Fleuret ships each finding with a replayable proof of concept, pushes it to Jira, Linear or Slack, and runs a retest after the fix, so the verification step does not start with rediscovering the bug.

How to shorten the verification cycle

  1. Reproduce the issue with exact steps, the affected version and proof of impact.
  2. Assign one owner and one due date so the fix does not drift across teams.
  3. Define the fix and add a regression test before the patch ships.
  4. Verify in staging with the same account type, role and data shape as production.
  5. Batch the retest when enough fixes are ready, instead of sending one ticket at a time.

Trade-off: batching too much delays closure, while sending fixes one at a time to an external tester inflates retest fees. Batch by release train, not by random ticket arrival.

Buy pentests with a cost-control playbook

What to put in the brief

The statement of work should list assets, environments, authentication model, test type, exclusions, business-critical flows, documentation and expected deliverables. If you do not define those, the vendor will, and you will pay for the ambiguity. Be as specific about what is out of scope as about what is in, including staging access, test data quality and whether the tester can touch real support or fraud workflows.

Urgency changes the price. Short-notice engagements usually carry a premium because the provider has to reshuffle work. If the business is forcing speed, at least know that you are paying for it.

What to compare in quotes

Compare quotes on the same scope, the same assumptions and the same retest terms. A cheap quote that leaves out authentication flows, ignores APIs or limits retesting is not cheaper, it is narrower. Force vendors to quote the same assets, the same window and the same deliverables, then ask what they excluded.

Certifications such as OSCP or PASSI matter, but they do not justify overspending on a badly defined scope. Good testers are useful. Good scoping saves more money.

Procurement checklist: ask whether the quote includes discovery, reporting, retest, rush handling and any assumption about staging access or test data. That is where hidden costs live.

Track three metrics that prove cheaper testing works

The metrics to watch

The right metrics tell you whether spend fell because the program got leaner or because coverage quietly collapsed. Track cost per validated critical finding, share of releases covered by automated gates and retest cost as a share of total testing spend. If all three move the right way together, you are buying less waste, not just less testing.

Two supporting metrics explain the movement: mean time to remediate high-severity issues, and the share of pentest findings your existing tools could already have detected. If that second number is high, you are paying people to rediscover what your stack should already catch.

A 90-day plan

  1. Weeks 1 and 2: inventory every test, owner, trigger and compliance driver.
  2. Weeks 3 and 4: tier your assets by risk and mark the deep-test surfaces.
  3. Weeks 5 to 8: automate the missing cheap checks in CI and staging.
  4. Weeks 9 to 12: renegotiate scope, retest terms and rush premiums with vendors.

Caution: if spend drops but escaped high-severity issues rise, the program is only cheaper on paper.

Buy fewer repetitions, not fewer safeguards

The best cost cuts come from cleaner scoping, earlier automation and tighter remediation, not from hollowing out the program. Remove duplicate tests first, move cheap checks into CI next, and only then renegotiate vendor work. That order keeps risk stable while stripping out the waste that hides in plain sight. If your release cadence has outgrown the yearly test, read why annual pentests are broken for SaaS.
