Continuous vs annual penetration testing: which cadence do you actually need?

An annual penetration test is a manual, time-boxed engagement, repeated every year and after major changes. Continuous penetration testing is recurring testing, usually automated scanning with periodic manual tests, sold as a subscription (PTaaS). Most SMBs pursuing SOC 2 or ISO 27001 need the annual manual test plus a retest. Teams shipping weekly to a large attack surface add scanning between tests.

Below you will find what each model catches, what it costs, what SOC 2, ISO 27001, PCI DSS and HIPAA say about frequency, and a hybrid pattern that covers most companies.

Three terms, three different things

The three terms get used interchangeably. They are not the same thing.

Annual penetration test. A manual test with a defined scope, a start date and an end date. Testers try to break in the way an attacker would: chaining weaknesses, abusing business logic, testing authorization between user roles. You receive a report with findings, severity and fix advice. The test is repeated once a year and after significant changes.

Continuous penetration testing. Testing that does not fully stop. In practice the continuous part is automated: scanners run daily or weekly against your assets and flag known vulnerabilities and misconfigurations. Manual testers step in at set intervals or when a scan result deserves a closer look.

Penetration testing as a service (PTaaS). A delivery model, not a test type. Booking, findings, retests and reports run through a platform instead of email and PDF. Many vendors bundle the platform with continuous scanning and sell the package as an annual subscription. Others, Budget Security included, use the platform to deliver manual tests priced per tester-day.

Continuous vs annual: side by side

	Annual penetration test	Continuous penetration testing
Cadence	Once a year, plus after major releases or infrastructure changes	Automated scans daily or weekly; manual testing quarterly or per release
What it catches	Authorization flaws, business-logic abuse, chained attacks, anything that needs a human to reason about your application	Known CVEs, missing patches, exposed services, misconfigurations, regressions between manual tests
What it misses	Vulnerabilities introduced between tests	Logic flaws and multi-step attacks that scanners cannot reason about
Cost model	Per engagement, scoped in tester-days	Annual platform subscription, often with a minimum commitment; manual hours on top
What auditors accept	Accepted as the pentest evidence for SOC 2, ISO 27001, PCI DSS and HIPAA when scope and dates fall inside the audit period	Scan output supports vulnerability-management controls; auditors still ask for a manual pentest report
Typical buyer	SMBs and mid-market companies with a few applications and a compliance deadline	Companies with large, fast-changing attack surfaces and a security team that triages daily findings

When continuous testing makes sense

Continuous testing earns its cost when the gap between two annual tests is where your risk lives. Four signals:

You deploy to production several times a week. A test from March says little about the code you shipped in September.
Your external attack surface is large or changes often. Dozens of domains, cloud accounts spun up by product teams, APIs that go live without a security review.
Someone will act on the alerts. A scanner that drops 200 findings a week into an inbox nobody reads adds noise, not security.
A customer or regulator asks for it. Some enterprise security questionnaires ask for continuous monitoring of the external perimeter, and PCI DSS requires quarterly vulnerability scans next to the annual pentest.

If two or more apply, add scanning. Keep the manual test: scanning complements it and does not replace it.

When an annual test plus a retest is enough

For most companies between 20 and 500 employees the honest answer is one well-scoped manual test per year, a retest after the fixes, and a second test when you ship something that changes the attack surface. That covers:

A SOC 2 Type II audit with one or two web applications and the cloud environment behind them.
ISO 27001 certification where vulnerability management is already handled by patching and a scanner you run yourself.
Customer due diligence, where the prospect wants a recent pentest report and proof that the findings were fixed.
A stable product with monthly or quarterly releases.

The retest matters more than people expect. A report with twelve open findings proves you were tested. A retest report proves you fixed them. Auditors and enterprise buyers read the second one.

What the standards actually say about frequency

Only PCI DSS writes a number into the text: requirement 11.4 of PCI DSS v4.0.1 asks for internal and external penetration testing at least once every 12 months and after significant changes, with a retest of the fixes (11.4.4), and requirement 11.3 adds vulnerability scans at least every three months. SOC 2 (criteria CC4.1 and CC7.1), ISO 27001 (Annex A control 8.8) and HIPAA (45 CFR 164.308(a)(8), a "periodic technical and nontechnical evaluation") ask for a process instead of an interval, and the number comes from your risk analysis and your auditor, who in practice expects a manual test inside each audit period. The standard-by-standard breakdown is in our guide on how often should you run a penetration test. The point for this comparison: PCI DSS already describes the hybrid below, and the other three accept it.

The hybrid pattern that covers most companies

Put the four frameworks side by side and the same pattern falls out. OWASP's Web Security Testing Guide makes the underlying point: a penetration test identifies a sample of the risks in a system and should not be the only testing technique you rely on.

One manual penetration test per year, scoped to the applications and infrastructure that handle customer, payment or health data.
Vulnerability scanning between tests, weekly or monthly, run by your own team or a scanning service. This is the part people usually mean when they buy continuous testing, and it is the part a scanner does well. Our guide on automated penetration testing explains what scanners find and what they miss.
A retest after the fixes, so your evidence shows closed findings instead of open ones.
A second manual test after major releases: a new authentication flow, a new public API, a cloud migration, an acquisition.

This costs a fraction of a continuous testing subscription and produces exactly the evidence auditors ask for.

How Budget Security fits

Budget Security does not sell a subscription, and we do not run an automated PTaaS scanning platform. We sell manual penetration tests, priced per tester-day, booked online and delivered through a portal. Our penetration testing as a service page explains that delivery model in full. The cadence is yours to set.

Register, add your assets, see the price. Your application is scoped into tester-days and the price is on screen before you commit. The full breakdown of pentest cost per test type is public.
From $985 per tester-day for US clients, EUR 849 in the Eurozone. No setup fee, no project-management fee.
Start within 7 days of booking. An earlier start depends on tester availability and carries an urgency surcharge.
Report within 48 hours after the test ends, with an executive summary and every finding with severity, CVSS score, impact, fix and replication steps. You pay after the report is delivered.
Track fixes in the portal. Set a status per finding, assign it to a developer, create a Jira issue with one click.
Book a retest as a one-tester-day add-on once the fixes are in.
Book a second test after a major release, the same way you booked the first. No annual commitment either way.

FAQ

Frequently asked questions

Can continuous testing replace the annual penetration test?

Not for an audit. The continuous part of nearly every offering is automated scanning, and SOC 2, ISO 27001, PCI DSS and HIPAA auditors ask for a manual penetration test report with scope, dates and tester qualifications. Continuous scanning sits between manual tests and catches regressions; it does not replace the test itself.

Is continuous penetration testing the same as vulnerability scanning?

Mostly, yes. The continuous component of nearly every continuous testing or PTaaS offering is automated scanning, with manual testers joining at intervals. The scanner finds known vulnerabilities and misconfigurations fast. The manual test finds authorization flaws, logic abuse and chained attacks. You need both, and only the manual part is a penetration test in the sense auditors use.

Does a PTaaS subscription satisfy SOC 2 or PCI DSS on its own?

Not if it only runs automated scans. SOC 2 auditors ask for a manual pentest report with scope, dates and tester qualifications. PCI DSS requirement 11.4 asks for penetration testing by a qualified resource and, separately, for quarterly scans under requirement 11.3. A PTaaS offering that includes manual tests by certified testers can satisfy both. Check that the report names the method and the testers' qualifications.
