Senior Expertise, Independent Practice
CyberRoof is a founder-led network security consultancy — built on 20+ years of hands-on enterprise delivery, not theory.
Vikas Shrivastav
CyberRoof is led by Vikas Shrivastav — a CISSP and CCNP-certified network security professional with over 20 years of hands-on experience across enterprise networking, security architecture, and infrastructure management. Vikas currently serves as Network Security Domain Lead at Admiral Insurance, where he leads a team of nine engineers and is responsible for the firm's network security domain — including current delivery of major infrastructure transformation programmes.
Prior to Admiral, Vikas spent nearly three years as Network Infrastructure Manager at Dartford and Gravesham NHS Trust, managing network and security infrastructure across a multi-site healthcare environment serving more than 500,000 people. Before that, a decade at Tata Consultancy Services saw him progress from Network and Security Engineer through to Head of Network Operations — with Jaguar Land Rover as the primary client, supporting six UK data centres, two international data centres, and over 100 remote sites globally.
CyberRoof exists to make that depth of enterprise experience accessible to organisations that need it — without the overhead of a large consultancy firm. Every engagement is handled by Vikas personally, bringing current, practising expertise to every client.
What Makes CyberRoof Different
Practising, Not Retired
Vikas is not a former practitioner — he is a current one. The advice you receive reflects what is being delivered in enterprise environments right now, not experience that stopped five years ago.
Genuinely Vendor-Neutral
No reseller agreements, no vendor partnerships, no commercial relationships with technology providers. Recommendations are made entirely on the basis of what is right for your environment.
Deliverable-Led Engagements
Every project is scoped to produce a clear, tangible output. Architecture documents. Assessment reports. Migration plans. You know what you are getting before the engagement starts.
Regulated Sector Credibility
Direct experience in financial services, healthcare, and automotive — sectors where security is not optional and where the consequences of getting it wrong are severe.
Honest, Direct Communication
No corporate layers, no account managers, no junior staff doing the work while a senior partner takes the fee. You work directly with Vikas from the first call to the final deliverable.
Practical, Not Theoretical
Recommendations are grounded in what works in real enterprise environments — not frameworks applied without context. If something is not feasible for your organisation, we will say so.
