How We Engage
No opaque retainers or vague SLAs. We work in one of three ways — and we are upfront about which model fits your situation before any engagement begins.
Fixed-Scope Engagement
Clear deliverables, defined timeline, agreed budget — no scope creep. We define exactly what will be delivered, when, and at what cost before work begins.
Ideal for: audits, VAPT engagements, assessments, investigations, compliance readiness, and advisory projects with a defined end state.
- Scoped statement of work before engagement starts
- Fixed timeline with milestone deliverables
- Clear acceptance criteria for every deliverable
- Post-engagement debrief included
Retainer
Ongoing advisory and response capacity on standby. When an incident happens or an urgent assessment is needed, there is no re-engagement lag — we are already briefed and ready to move.
Ideal for: organisations with recurring security needs, incident response readiness, VAPT cycles, or regular compliance advisory requirements.
- Guaranteed response SLA for incidents
- Monthly advisory hours included
- No re-engagement ramp-up on urgent work
- Quarterly posture review included
Expert Advisory
Direct access to senior cybersecurity practitioners for strategic guidance on security programme maturity, incident readiness, compliance, and architecture.
Ideal for: organisations that need ongoing security expertise without a full retainer.
- Direct access, no account management layer
- Strategic, not operational guidance
- Flexible scheduling around your team
- Written guidance notes included
Cybersecurity Practitioners, Not Consultants
Every engagement is led by someone who has done this work — not a junior analyst reading from a checklist. Our co-founders each bring a decade of live digital forensics, incident response, and security assessment experience, working on complex cases for organisations across India.
Services — Common Questions
Do you handle active incidents, or only post-incident forensics?
Both. We respond to active incidents — containment, triage, and eradication — and we conduct post-incident forensic investigations to reconstruct exactly what happened. If you are in the middle of a breach, contact us immediately.
What types of devices and platforms do you investigate?
Windows, macOS, and Linux systems (disk and memory); Android and iOS mobile devices; cloud environments including AWS, Azure, and Google Cloud; SaaS platforms; and network captures (PCAP).
Do you provide VAPT and security assessments beyond DFIR?
Yes. We deliver vulnerability assessment and penetration testing, audit and compliance readiness, security infrastructure design, cybersecurity posture assessments, and insider threat investigations — in addition to our DFIR services.
Can you help with ISO 27001, SOC 2, or other compliance readiness?
Yes. We conduct gap assessments, control reviews, and audit preparation support for ISO 27001, SOC 2, HIPAA, PCI DSS, GDPR, DPDP Act, NIST CSF 2.0, and applicable regulatory frameworks.
What is the difference between a retainer and a fixed-scope engagement?
A fixed-scope engagement has a defined deliverable and timeline — it ends when the work is done. A retainer keeps Cyfonix on standby for your organisation on an ongoing basis with a guaranteed response SLA.
Can you work on-site?
Yes. Incident response, forensic investigations, and certain assessments require on-site access. We are based in Ahmedabad and travel across India for engagements.
