Virtual CISO (vCISO) Services
Not every organisation needs a full-time Chief Information Security Officer — but every organisation needs the leadership one provides. Aesparrow’s Virtual CISO (vCISO) service embeds senior security leadership directly into your business, giving you strategy, governance and executive-level direction without the cost of a full-time hire. We build and run a security programme aligned to your business goals, your customers’ expectations and the compliance frameworks you need to meet.
Your vCISO owns the things that fall between engineering and the boardroom: a prioritised security roadmap, policies and standards, risk management, vendor and third-party assessments, customer security reviews, and board-level reporting. Whether you are answering enterprise security questionnaires, preparing for ISO 27001 or SOC 2, or simply maturing your posture, you get a seasoned practitioner steering the programme and translating technical risk into business decisions.

Frequently Asked Questions
How is a vCISO different from a consultant?+
A consultant advises on a project; a vCISO owns and runs your security programme over time — accountable for strategy, governance, risk and reporting, and acting as your senior security point of contact.
Is a vCISO right for a small or mid-sized company?+
Especially so. It gives you enterprise-grade leadership on a fraction of a full-time salary, which is ideal when you are scaling, entering enterprise deals, or pursuing certification.
Can the vCISO help us pass customer security reviews?+
Yes. Handling security questionnaires, evidence and enterprise buyer reviews is a core part of the service.
How much time is included?+
Engagements are flexible — from a few days a month to a more hands-on programme — scoped to your needs and stage.

Web Application VAPT
Your web application is the front door to your business — and the first thing an attacker probes. Aesparrow’s Web Application VAPT (Vulnerability Assessment and Penetration Testing) combines deep manual testing with trusted tooling to find the flaws that automated scanners miss: broken access control, business-logic abuse, injection, and authentication weaknesses. You get a clear, prioritised picture of what a real attacker could do, and exactly how to fix it before it costs you.
API Security Testing (API VAPT)
APIs power your apps, partners and integrations — and they’re now the most attacked part of most modern platforms. Because APIs expose business logic directly, a single broken authorisation check can leak every customer’s data. Aesparrow’s API Security Testing (API VAPT) is built around the OWASP API Security Top 10 and goes deep on the flaws automated tools consistently miss: broken object-level authorisation (BOLA/IDOR), mass assignment, and business-logic abuse.
Red Team Assessment
A penetration test answers "is this system vulnerable?" A red team assessment answers a harder, more valuable question: "if a determined attacker targeted our business, would we detect and stop them?" Aesparrow’s red team runs a goal-based, adversary-style simulation across people, process and technology — emulating real threat actors to test your detection and response, not just your patch levels.
