How much does a traditional manual pentest cost?

A typical manual web-application pentest costs $20,000 to $50,000 per engagement and runs once or twice a year. Pricing scales with scope and tester seniority. HackZero starts at $2,999/mo and runs continuously, so a year still costs less than one mid-range manual engagement. Teams of 5 or fewer can apply for the $499/mo Startup deal.

When does a manual pentest still make sense over AI?

Three situations: (1) your auditor explicitly requires human-led testing (DORA TLPT, CBEST, formal NIST 800-53), (2) you're threat-modelling novel architecture pre-release, or (3) you need adversary simulation spanning social engineering, physical, and network layers. HackZero is web-app and API scoped and complements (rather than replaces) these mandated tests.

Will AI pentesting be accepted by SOC 2 / ISO 27001 auditors?

Yes. Auditors require evidence of regular pentesting; the form of the test is not prescribed. HackZero ships signed, timestamped attestation letters per run that map to SOC 2 CC4.1, ISO 27001 A.8.29, PCI-DSS 4.0 Req. 11.4, and HIPAA 164.308(a)(8). Auditors accept them as primary or supplementary evidence depending on framework.

How does continuous testing compare to once-a-year coverage?

Coverage drift is the gap between a test and what's actually in production. Manual: months. HackZero: days. If you ship to production more than once a month, an annual pentest reflects an application that no longer exists, so most findings arrive after the code that introduced them has already shipped to customers.

HackZero vs. Manual Pentest

Manual penetration testing is older than continuous integration. It still has a job. So does HackZero. Different jobs. Here's the honest breakdown.

Side by side

	Manual quarterly pentest	HackZero
Reads your code	Sometimes	Yes, code-aware via GitHub
Cadence	Once or twice a year	Every week
Lead time	4 to 12 weeks to schedule	Minutes
Cost	$20K to $50K per engagement	From $2,999 a month
Deliverable	PDF report, often 100+ pages	Findings into your issue tracker
Re-test after fix	New engagement, new invoice	Built in
Coverage drift between tests	Months	Days
Scaling cost	Linear with team size and apps	Flat per tier
Auditor acceptance	Yes, attestation letter	Yes, signed attestation per run
Replaces mandated TLPT (DORA, CBEST)	Yes	No, complements between mandated tests

When to hire a manual pentester

Your auditor explicitly requires a human-led engagement (DORA TLPT, CBEST, formal NIST 800-53 assessment).
You're doing pre-release threat modelling on novel architecture and want a creative human in the loop.
You need a deep adversary simulation that spans social engineering, physical, and network layers, not just web app.

When to run HackZero

You need continuous coverage between mandated annual tests.
Your team ships to production multiple times per week and quarterly testing doesn't reflect what's live.
You want findings in your issue tracker, not in a PDF that ages out in 30 days.
Your budget for offensive security is a monthly software line item, not a $50,000 quarterly engagement.

Bottom line

Most security programs need both. The mandated, deep, human-led engagement once a year for the auditor's signature. HackZero every week between those engagements to keep the picture current and catch what regressed. You stop paying $25K twice a year to discover what shipped to production three months ago.
