4 Engagement Models · Platform-Driven Delivery

How we work with you.
Pick the model that fits.

Every engagement runs through our Lemon platform with daily progress tracking, AI-augmented testing, and multi-layer quality review — whether it's a single assessment or a year-long partnership.

Engagement Models

Four ways to engage

From a single penetration test to a dedicated security team, choose the model that matches your security needs and operational cadence.

One-Time Engagement

Project-based delivery

Standard project-based engagements with a clear scope, fixed quote, and defined deliverables. Ideal when you need a specific assessment done right, without ongoing commitments.

Scope → Quote → Order → Deliver

Best for

  • Single penetration tests or VAPT
  • Compliance audits (CERT-In, PCI DSS, ISO 27001)
  • One-off application security assessments
  • Pre-launch security validation

Annual Contract

Planned annual coverage

A defined annual scope covering multiple engagements through the year. Fixed pricing, predictable budgets, and priority scheduling for all assessments.

Fixed annual pricing with priority scheduling

Best for

  • Quarterly VAPT cycles for enterprises
  • Continuous compliance maintenance
  • Multiple applications and infrastructure
  • Annual security program coverage

On-Demand Rate Contract

Flexible, usage-based

Pre-agreed rates per IP, per application, or per man-day. Minimum utilisation commitment with agreed turnaround timelines. Trigger assessments on-demand, including CI/CD integration via our Lemon API.

CI/CD integration via Lemon API

Best for

  • DevSecOps teams needing CI/CD-integrated testing
  • MSSPs and channel partners
  • Organisations with variable testing volumes
  • Agile teams with frequent release cycles

Dedicated Team

Embedded security resources

On-site or remote dedicated security professionals for a defined period. Your own security team, managed by Security Brigade, with full platform access and reporting.

On-site or remote, fully managed

Best for

  • Large-scale transformation programs
  • Sustained red team operations
  • In-house SOC augmentation
  • Long-term security programs (3–12 months)
