CREST-Certified Bug Bounty Programme Design and Management for UK Businesses
Bug bounty programmes attract continuous external security research, but only if scoped, triaged, and paid out professionally. We design and manage bug bounty programmes for UK businesses: pre-bounty hardening, scope definition, hunter triage, payout coordination, and CVSS-aligned severity adjudication.
“Operational requirements were always respected, with clear communication on every milestone.”

Bug bounty without management = continuous fire-fighting. Bug bounty with management = continuous security uplift.
Public bug bounty programmes attract thousands of submissions; most are low-severity, duplicate, or out-of-scope. Without proper triage, your security team drowns in noise. Hunters get demotivated by slow responses. Critical findings get lost. Your programme reputation deteriorates and the best researchers stop submitting.
Our bug bounty management combines pre-bounty hardening (we run a focused pen test before launch to remove the obvious findings), professional triage (CREST-certified consultants validate every submission), CVSS-aligned severity adjudication, payout coordination, and ongoing programme tuning. Reports satisfy ISO 27001 A.5.7 / A.8.8 vulnerability management evidence and provide auditors with a documented continuous security testing process.

Programme Design
Scope definition, exclusion list, severity matrix, payout structure, ROE, legal sign-off, public/private decision.
Pre-Bounty Hardening
Focused pen test before bounty launch. Removes the obvious findings. Reduces total bounty payout by 30-50% over the programme lifetime.
Platform Selection
HackerOne / Bugcrowd / Intigriti / Immunefi / YesWeHack / self-hosted. Platform-agnostic recommendation based on sector + budget.
Researcher Triage
First-line triage of every submission. Out-of-scope filtering, duplicate detection, reproducibility validation, severity adjudication.
CVSS Severity Adjudication
Independent CVSS-aligned severity scoring. Reduces hunter disputes. Aligns payout to genuine business impact.
Hunter Communication
Professional, prompt hunter responses. Maintains researcher engagement. Protects programme reputation in the bounty community.
Payout Coordination
Monthly payout cycle, dispute resolution, hunter relationship management, top-researcher engagement, hall of fame programme.
Programme Tuning
Quarterly review of submission rate, severity distribution, payout efficiency. Scope adjustments to attract specific researcher skill sets.
Internal Engineer Coordination
Liaison with your engineering teams for finding remediation. Ticket creation, severity prioritisation, retest validation.
Compliance Mapping
Bug bounty findings mapped to ISO 27001 A.8.8 vulnerability management evidence and SOC 2 CC7.1 monitoring evidence.
VDP Programme
Vulnerability Disclosure Programme (no-payout) operation as a precursor to or alongside paid bounty.
Bug Bounty Audit
Annual audit of bug bounty programme effectiveness: submission quality, payout efficiency, MTTR, repeat-finding rate.
FOUR-PHASE METHODOLOGY

COMPLIANCE READY
Bug Bounty Reports Mapped to Every Framework
Bug bounty as a continuous vulnerability management control. Evidence accepted across compliance frameworks.
ISO 27001 A.8.8
Vulnerability management: bug bounty provides continuous external testing evidence ISO 27001:2022 increasingly expects.
ISO 27001 A.5.7
Threat Intelligence: bug bounty submissions are a threat-intelligence source about adversary tradecraft.
SOC 2 Type II
CC7.1 vulnerability identification, CC7.2 monitoring evidence accepted by SOC 2 auditors.
NIS2
Essential services obligations include continuous vulnerability management; bug bounty is one of the strongest evidence sources.
FCA / PRA Operational Resilience
Continuous vulnerability awareness for Important Business Services: bug bounty supports severe-but-plausible scenario evidence.
NCSC Vulnerability Disclosure
Aligned to NCSC Vulnerability Disclosure Toolkit, UK government’s recommended VDP / bug bounty practice.
Bug Bounty Programmes for Your Sector
Bug bounty platform selection and scope vary by sector. We design programmes that attract the right researcher skill sets.
Fintech
Fintech bounties (FCA-regulated): typically Bugcrowd, HackerOne, Intigriti. Specific scope around payment APIs, KYC flows.
SaaS
SaaS bounties: HackerOne, Bugcrowd. Focus on tenant isolation, OAuth flows, GraphQL endpoints.
Healthcare
Healthcare bounties: typically private Bugcrowd / HackerOne with selective researcher invitation due to PII sensitivity.
Insurance
Insurance bounties: private programmes focused on quote/bind APIs, claims-data exposure, broker portals.
Law
Law firms: VDP-only typically; full bounty rare due to privileged-data sensitivity.
Public Sector
Public sector VDP: aligned to NCSC Vulnerability Disclosure Toolkit, /security.txt publication, public-facing.

Frequently Asked
What is a bug bounty programme?
A bug bounty programme is a continuous external security research initiative where independent researchers (hunters) submit security vulnerabilities in exchange for cash bounties. Programmes can be public (open to all hunters) or private (invitation-only). Bug bounty complements (does not replace) periodic penetration testing.
How is bug bounty different from penetration testing?
Pen testing is point-in-time, scoped, and goal-driven. Bug bounty is continuous, broad-scope, and adversary-driven. Pen testing produces audit evidence. Bug bounty produces continuous discovery. Use both: pen testing for compliance, bug bounty for ongoing resilience.
Do we need to be public on a platform?
No. Many UK businesses run private invitation-only programmes on HackerOne or Bugcrowd, or self-hosted Vulnerability Disclosure Programmes. Public is highest-volume; private is highest-quality. We recommend based on your sector, scope, and budget.
How much should we budget for bounty payouts?
Typical UK ranges: low-severity £100-£500, medium £500-£2,000, high £2,000-£10,000, critical £10,000-£50,000+. Total annual payout depends on scope and submission volume. SaaS programmes typically £30k-£150k/year; fintech programmes typically £100k-£500k/year.
How long does pre-bounty hardening take?
Pre-bounty hardening is a focused pen test before bounty launch. Typical engagement: 5-10 working days. Removes the obvious findings (the issues every reasonable researcher would find), reducing baseline bounty payout by 30-50% over the programme’s first 12 months.
How do you triage submissions?
Every submission validated by a CREST-certified consultant. Out-of-scope filtered, duplicates detected, reproducibility validated, CVSS-scored. Hunter receives professional response within 24-48 hours. Genuine findings escalated to your engineering team for remediation.
Can you handle our existing programme?
Yes. We can take over an existing programme on HackerOne, Bugcrowd, Intigriti, or self-hosted platforms. Migration is non-disruptive; we co-triage with your existing team during the handover, then assume full triage responsibility.
Will bug bounty conflict with our pen testing?
No. Bug bounty and pen testing are complementary. We coordinate scope to avoid duplication; pen testing covers controlled-time-frame audit evidence, bug bounty covers continuous discovery. Many clients use bug bounty findings as input to next year’s pen test scope.
How does bug bounty support ISO 27001?
ISO 27001:2022 explicitly references continuous vulnerability management (A.8.8) and threat intelligence (A.5.7). A documented bug bounty programme (with triage workflow, payout structure, and remediation evidence) provides direct evidence ISO auditors increasingly require.
Can you run a Vulnerability Disclosure Programme (no-payout)?
Yes. VDP is a no-payout precursor to (or alternative to) paid bounty. We set up the policy, publish /security.txt, run triage, and coordinate remediation. UK public-sector and many enterprise organisations choose VDP-only as their initial step. Aligned to NCSC Vulnerability Disclosure Toolkit.
Are your triage consultants UK-based?
Yes. Triage team is UK-based. Hunters submitting to managed programmes interact with our UK-based consultants: UK time zone, UK English, UK GDPR-compliant data handling.
Do you sign NDAs?
Yes. Standard NDA before any programme scope discussion. We operate under a project-specific master agreement that includes hunter-relationship management and post-engagement data destruction.
