Hardened Client Portal Rebuild for a Cybersecurity Consulting Firm

Overview

Rebuilt the client portal for a cybersecurity consulting firm — an unusually high-stakes rebuild, given that the firm's own credibility depends on practicing what it advises clients to do. The new portal was architected around a minimal attack surface, strict access controls per client engagement, and hardened session and file-upload handling for the sensitive security assessment reports clients access through it. We conducted our own internal security review of the rebuild before handoff, given the firm's justifiably high bar for anything hosting its own client deliverables. The rebuild also replaced an aging portal that had itself become a liability the firm's own team had flagged internally. A cybersecurity consulting firm's own client portal had become an aging liability its team had flagged internally, an uncomfortable position for a firm whose credibility depends on practicing what it advises clients to do. We rebuilt the portal architected around a minimal attack surface, strict per-engagement access controls, and hardened session and file-upload handling for sensitive security assessment reports, with our own internal security review conducted before handoff given the firm's justifiably high bar. We treated this rebuild with an unusually high bar given the firm's own business depends on credibility in exactly this area, conducting our own internal security review before handoff rather than waiting for the client to request one. The rebuild replaced the aging portal in a staged migration to avoid disrupting active client engagements. The firm now has a client portal that reflects the security standard it holds its own clients to, removing a liability its team had flagged as reputationally risky.
