In Boulder, the first pentest usually comes from a sales deal, not a breach: a security questionnaire, a SOC 2 auditor or an investor's diligence checklist. Zero Day Security gives early- and growth-stage teams a manual, fixed-price test sized to the product they actually have.
Seed to Series B SaaS and API-first companies preparing for their first SOC 2 report or first large customer, whose buyers will probe the product themselves.
Teams shipping LLM features, RAG search or autonomous agents on top of customer data, where the serious issues sit where the model meets your access controls.
University spinouts moving from lab prototype to commercial platform, and direct-to-consumer brands running storefronts, subscriptions and loyalty apps.
Multi-tenant SaaS and REST, GraphQL and WebSocket APIs, with attention to tenant isolation, BOLA/IDOR, broken authentication and business-logic flaws scanners miss.
Prompt injection, jailbreaks, system-prompt and data leakage, RAG poisoning and agents calling tools they shouldn't, tested against the OWASP Top 10 for LLM Applications.
Your production perimeter, from exposed storage and admin panels to forgotten staging hosts, plus on-site internal and Wi-Fi testing for office or lab networks.
Auditors commonly expect a pentest as evidence under CC4.1 and CC7.1. For a Type II report, testing early in the observation period leaves time to fix and retest.
Often the real deadline. Buyers want a recent third-party report, an executive summary they can file and proof that critical findings were fixed.
Health startups use pentests to support HIPAA's risk analysis, and PCI DSS 11.4 applies if you handle card data or control the payment page.

Before the first deal or audit that will ask for one. In practice, that means scheduling it when your core product is stable, when an enterprise security review lands, or early in a SOC 2 Type II observation period. Testing too early, before authentication and multi-tenancy are settled, means retesting much of it later. Testing too late leaves no time to fix findings before the report is due.
Yes. AI and LLM features are tested for prompt injection, jailbreaks, leakage of system prompts or other customers' data, poisoned retrieval in RAG pipelines, and agents misusing tools or permissions. Testing follows the OWASP Top 10 for LLM Applications. AI features are often scoped alongside the surrounding web app and API, because many of the serious issues sit where the model meets your access controls.
Either can work. Production gives the most realistic result, and testing is non-destructive and scheduled to avoid disruption. Staging is a good choice when it mirrors production closely and you'd rather not touch real customer data. Many startups test the application in staging and the external perimeter in production. The report states exactly which environment was tested, which auditors and customers will check.
It can be, if your product is small: a single application or API with up to two user roles and around twenty pages or endpoints. Auditors care that the test covers the systems in your SOC 2 scope. If your platform is larger, the Standard Assessment is the better fit. The scoping call will confirm which package matches your scope.
It starts with a free scoping call to agree targets, test windows and rules of engagement, and you receive a fixed price in writing. Testing is manual and non-destructive, and critical findings are reported immediately. The report includes an executive summary, CVSS-scored findings with evidence and remediation steps, and a methodology section for auditors. Once you've fixed the findings, a free retest confirms what's closed.
Every test is performed by a CREST-certified tester who also holds CREST CPSA, OffSec OSCP, OSWA, OSWP and OSAI, plus the HTB Certified Offensive AI Expert (COAE). All are practical, exam-based credentials. The same tester handles your engagement from scoping to retest, and every engagement is fixed-price with a free retest included.
