Why SecByte
Evidence-driven security work, delivered like a consultancy should deliver it.
Experienced cybersecurity professionals, confidential handling of your data, and a process designed around the way engineering teams actually fix things.
Human-led testing
Every engagement is run by an experienced consultant, not a scanner with a logo on the report.
AI-assisted analysis
Automation and AI accelerate discovery, correlation and triage. They never make the final call.
Manual validation
Findings are reproduced and evidenced by hand, so false positives never reach your backlog.
Professional reporting
Executive summary, technical detail, CVSS scoring, evidence and clear remediation steps.
Secure client workflow
Scoped access, signed URLs for reports and evidence, and a private portal per organisation.
Retesting included
Once you remediate, we verify the fix and reissue the report with updated finding status.
