What’s driving your test?
-
An audit is coming up
SOC 2, ISO 27001, or HIPAA. We scope the test to the systems your auditor will review.
-
A customer sent a security review
A questionnaire or vendor review is holding up a deal. Get a current, independent test of the product they’re asking about.
-
Your cyber insurer wants a test
An external network test, plus a phishing campaign if your insurer asks for one, with a letter you can give your broker or insurer.
-
You’re shipping AI features
Prompt injection, data leaks, and agent abuse, tested across the whole feature, with a letter you can share with your customers.
A scanner tells you what’s vulnerable. A tester tells you what’s exploitable.
We run automated tools on every pen test as a starting point. The most serious findings usually take a person who understands what your application is for.
Automated scanning
- Finds known CVEs and common misconfigurations
- Covers broad ground quickly
What a HackNow tester adds
- Tests authorization between users, roles, and tenantsA 2025 peer-reviewed ACM CCS study says reliable broken-access-control detection remains limited; in its benchmark, a commercial scanner with an authorization extension caught 54% of 57 unauthorized-modification flaws.Source: Liu et al., ACM CCS 2025, BACScan: Automatic Black-Box Detection of Broken-Access-Control Vulnerabilities in Web Applications (2025) (PDF)
- Tests business logic: pricing, workflows, approvals, and limitsOWASP’s Web Security Testing Guide says business-logic flaws “cannot be detected by a vulnerability scanner.”Source: OWASP Foundation, Web Security Testing Guide v4.2: Introduction to Business Logic (2020)
- Chains low-severity issues into real attack paths
- Verifies every finding by hand before it’s reported
- Writes proof-of-concept evidence and reproduction steps
- Retests each fix against the original finding
Why it matters
31%
A report your engineers will actually use.
Each finding is verified by hand and written so a developer can reproduce it and fix it. Every report is reviewed by a second tester before delivery. Leaders get a plain-English summary. Auditors and customers get an attestation letter.
Methodology based on OWASP WSTG v4.2, ASVS 5.0, API Security Top 10 (2023), MASVS v2.1, Top 10 for LLM Applications (2025), PTES, NIST SP 800-115, and MITRE ATT&CK®.

- Executive summaryOverall risk, key themes, and priorities, in plain language for leadership.
- Technical findingsSeverity rating, CWE reference, affected assets, evidence, and reproduction steps for each one.
- Attack pathsHow separate issues chain together into real impact.
- Remediation guidanceSpecific fixes for your stack, written for the engineers who will apply them.
- Attestation letterThe test dates, scope, method, and results, to share with customers, auditors, or your insurer.
- Retest resultsAn updated report and attestation letter once we’ve verified your fixes.
Six kinds of penetration test, each led by a tester.
Penetration testing
Manual testing of the systems attackers reach first.
-
Web applications
Authenticated, manual testing of your web apps, from the login page to business logic.
A regular user can approve their own refund.
-
APIs
REST, GraphQL, gRPC, and WebSocket APIs tested for authorization flaws and data exposure.
Changing one letter of a booking code returns another guest’s booking.
-
Networks and Active Directory
External perimeter, internal network, Active Directory, and on-site wireless testing.
A help desk account is three steps from Domain Admins.
-
Cloud (AWS, Azure, Google Cloud)
AWS, Azure, Google Cloud, and Kubernetes tested for misconfiguration and privilege escalation.
A build server’s role can read every production bucket.
-
Mobile apps
iOS and Android apps tested on instrumented devices: what they store, send, and trust.
A client-side flag unlocks paid features.
-
AI and LLM applications
Prompt injection, data leakage, and agent abuse testing for AI features and LLM applications.
The support bot can be talked into showing other customers’ tickets.
Adversary simulation
Find out whether your people and your detection would stop a real attack.
Assessment and training
Code and design review, vulnerability assessments, and hands-on training from working testers.
- Code review and threat modeling Design reviews and manual source code review that find security flaws before they ship.
- Vulnerability assessments Authenticated internal and external scanning, reviewed and prioritized by a tester.
- Security training Hands-on training for developers and security teams, plus awareness training for all staff, taught by working testers.
What you can count on, from scoping to retest.
Here’s how a pen test runs and what we commit to at each stage.
- Reply within one business day
Scope
You get a fixed-fee proposal and written rules of engagement. Testing can usually start within 5 business days of signing.
- Typically 1 to 3 weeks
Test
All testing is performed by HackNow’s own US-based testers. We never pass your test to another firm. We work your targets by hand, backed by tooling.
Critical findings within 24 hours of confirmation
Critical findings are reported within 24 hours of confirmation, not held for the report.
- Within 5 business days after testing ends
Report
An executive summary for leadership and technical findings your engineers can act on, then a walkthrough call with your team. Final report delivered within 5 business days after testing ends.
- Within 90 days of the final report
Retest
One retest of reported findings within 90 days of the final report, included in the price. We verify each fix and issue an updated report and attestation letter.
Our six published commitments are written into our standard proposal. See all six
We started by teaching people to hack. We still do.
Hands-on hacking education came first, with a training platform and courses. Teaching shows in our reports: we explain why an issue happened as well as how to fix it.
Common questions before an engagement
Anything else? Ask us directly.
How much does a penetration test cost?
Every engagement is a fixed fee after a free scoping call. Starting prices for the smallest scope: web applications from $5,000 per application (including its own API), external network tests from $5,000, APIs from $8,000 per API, AI features from $5,000, and cloud environments from $10,000 per environment. Your price depends on the applications, user roles, API endpoints, IP addresses, or cloud accounts in scope, and it won’t change once testing starts unless the scope does. One retest of reported findings within 90 days of the final report is included.
Starting prices in US dollars for the smallest scope of each service, reviewed October 2026. Your price is a fixed fee, set in a written proposal after a free scoping call.
How long does a test take, and when can you start?
Testing can usually start within 5 business days of signing. Most web application, API, and network tests take one to three weeks of testing. Start dates are agreed during scoping, so tell us your deadline when you ask for a quote.
Isn’t a vulnerability scan enough?
A scan is automated: it checks your systems for known issues. A penetration test adds testers who confirm what’s actually exploitable, test authorization and business logic, and chain small issues into real attack paths. NIST SP 800-53 Rev. 5 (CA-8) says penetration testing “goes beyond automated vulnerability scanning.” We still run scanners in every pen test for breadth.

Who does the testing?
Our own US-based testers. We never pass your test to another firm. Each tester is an individual contractor engaged directly by HackNow, LLC under a written agreement. Certifications held across our testing team include OSCP, CRTO, CISSP, CCSK, and CompTIA PenTest+. Our testers have delivered 100+ penetration tests over their careers, including engagements for partner security firms.
Will testing disrupt production?
Testing is planned to avoid disruption. We agree on testing windows, source IP addresses, and emergency contacts before we start. Denial-of-service and destructive testing are never performed without written approval, and you can pause testing at any time with one message. If anything we do seems to affect a system, we stop testing and call your emergency contact before we continue. If you have a staging environment that mirrors production, we’re happy to test there.
What will our auditor, customer, or insurer get?
Reports document the scope, methodology, and dates that assessors typically look for. You also get an attestation letter to share with customers, auditors, or your insurer without handing over the full technical report. Your auditor decides what evidence it accepts. A full sample report, for an invented client, is available on request.
Is a retest included?
Yes. One retest of reported findings within 90 days of the final report is included in the price. We verify each fix and issue an updated report and attestation letter. Phishing campaigns don’t include a retest.
Can we sign an NDA first, and how do you handle our data?
Yes. We’ll sign a mutual NDA before scoping, or send ours. Evidence is handled under the confidentiality and retention terms in your contract, and we access sensitive data only as far as needed to prove impact.
Send an NDA before we discuss details How we handle your data
Can a penetration test find every vulnerability?
No test can promise that. A penetration test is a time-boxed assessment of the agreed scope at a point in time. We focus testing time where the risk is highest and report everything we confirm.
