Industry
Supervised, audited, and targeted more than most.
Financial institutions carry the heaviest supervisory expectations and the most motivated adversaries. Gryffin works with banks, NBFCs, insurers, brokers and payment intermediaries across regulatory compliance, resilience, fraud investigation and the day-to-day security operations that supervisors increasingly want evidence of.
Industry Challenges
Supervisory expectations that keep rising
IT governance, cyber resilience, incident reporting and outsourcing oversight are examined in detail, and documentation alone no longer satisfies an inspection.
Payment environments with wide scope
Cardholder data spreading across the estate turns a contained compliance obligation into an enterprise-wide one.
Third-party and concentration risk
Core systems increasingly run with providers, and supervisors expect documented oversight and exit planning for each.
Fraud that looks like legitimate activity
Account takeover, payment redirection and insider activity present as normal transactions until someone is looking for the pattern.
Applicable obligations vary by entity class and jurisdiction. Engagements begin by establishing which supervisory expectations, data residency requirements and reporting timelines actually apply to you.
Services
Built for the inspection, not just the policy file.
Financial-sector supervision looks past documentation to whether governance actually operates: who approved what, when it was reviewed, and what the board was told. Gryffin builds compliance programmes for regulated lenders and intermediaries that produce that evidence as a by-product of running the business, and prepares the organisation for inspection rather than reacting to it.
What the engagement covers.
Applicability and gap assessment
Establishing which supervisory expectations apply to your entity class and assessing current governance, controls and documentation against them.
IT and cyber governance framework
Board and committee structure, policy hierarchy, roles and accountabilities, risk appetite and escalation thresholds, documented and operating.
Cyber resilience and continuity
Recovery objectives, incident classification and reporting workflow, continuity testing, and the evidence that testing occurred.
Audit trail and log governance
Retention, integrity and reviewability of logs across critical systems, and the review cadence that supervisors expect to see documented.
Third-party and outsourcing governance
Due diligence, contractual control requirements, ongoing monitoring and exit planning for technology and service providers.
Inspection readiness
Evidence pack assembly, board reporting templates, and rehearsal with your internal team before the supervisory visit.
What you receive
Programmes designed around inspection
We build toward the question a supervisor actually asks - show me the evidence this operated - rather than toward a policy document that describes what should happen.
Governance and engineering in one team
Where a supervisory expectation requires a technical control (logging, access review, resilience testing), Gryffin's engineers implement it. The gap between policy and control is where most findings originate.
Board-ready reporting
Reporting packs are written so directors can discharge oversight duties without a translation layer, and so the minutes evidence that oversight occurred.
Mapped to ISO 27001 where it helps
Where you already hold or want ISO certification, the regulatory control set is mapped to it so one control environment serves both.
Illustrative. Scenarios drawn from common engagement patterns.
An inspection window approaching, with governance undocumented
Outsourced technology with no oversight record
Incident reporting obligations nobody could operationalise
The cheapest control is the one you took out of scope.
Most PCI DSS programmes are expensive because too much of the estate is in scope. Gryffin starts by mapping where cardholder data actually flows, then reduces the assessed environment through tokenisation, redirection and segmentation before implementing controls - because every system removed from scope is a system you never have to assess, monitor or evidence again.
What the engagement covers.
Cardholder data discovery and flow mapping
Establishing where card data enters, is processed, transmitted and stored - including the copies nobody documented.
Scope reduction design
Tokenisation, redirection, outsourced capture and architectural change to remove systems from the cardholder data environment entirely.
Network segmentation and validation
Segmentation design between the CDE and the rest of the estate, plus the segmentation penetration testing PCI DSS requires to prove it holds.
Control implementation
Implementation across the applicable requirements - access control, logging and monitoring, encryption, vulnerability management, secure development and change control.
Evidence preparation and SAQ/ROC support
Assembling the evidence set, completing the appropriate self-assessment questionnaire, or preparing for a QSA-led Report on Compliance.
Ongoing compliance operations
Quarterly scanning, annual testing, log review and the recurring obligations that keep compliance continuous rather than annual.
What you receive
Scope reduction first, controls second
We treat scope as the primary lever. Reducing the cardholder data environment lowers assessment cost, monitoring cost and breach exposure simultaneously - and it is work most programmes skip.
Segmentation we can prove
Our testers validate segmentation independently of the engineers who built it, which is both a PCI requirement and the only honest way to confirm the boundary holds.
Implementation and assessment support under one roof
Gryffin's engineers deploy the logging, encryption, access control and monitoring the standard requires, so the gap between the requirement and a working control does not become your problem to solve.
Continuous, not annual
The controls are instrumented for continuous evidence, so quarterly and annual obligations are checkpoints rather than a scramble.
Illustrative. Scenarios drawn from common engagement patterns.

Someone is watching at 3am. And they answer.
Attacks do not arrive during office hours; they arrive when nobody is looking. A managed SOC gives you continuous coverage without staffing three shifts - but only if the detection content is built for your environment and the escalation arrives with an investigation already attached. Gryffin builds the detection, runs the monitoring, and escalates with a recommendation rather than a raw alert.
What the engagement covers.
Log source onboarding and normalisation
Identifying the telemetry that matters, onboarding it, and normalising it so correlation is possible across endpoint, identity, network, cloud and application sources.
Detection engineering
Detection content written and tuned for your environment and industry, mapped to MITRE ATT&CK, with coverage gaps documented rather than glossed over.
24x7 monitoring and triage
Continuous analyst coverage with alert triage, enrichment and investigation before anything reaches you.
Escalation and response support
Agreed escalation paths, severity definitions and response-time commitments, with pre-authorised containment actions where you want them.
Threat hunting
Scheduled hypothesis-driven hunts looking for what the detections would have missed, feeding new content back into the platform.
Reporting and coverage review
Monthly operational reporting and quarterly coverage review against ATT&CK, with a roadmap for closing remaining gaps.
What you receive
Detection built for you, not shipped as defaults
Default SIEM content produces volume, not value. Our engineers build and tune detections against your log sources and business processes, and we measure the true-positive rate rather than the alert count.
Coverage you can see
Detection coverage is mapped against MITRE ATT&CK, so you know which techniques you would catch, which you would miss, and what closing each gap costs. Nobody has to take the coverage claim on trust.
Escalations that arrive with an answer
An alert reaches you triaged, enriched and with a recommended action. Where you have pre-authorised containment, the action has already been taken and you are told what and why.
Bring your own platform, or ours
We operate on Microsoft Sentinel, Splunk, QRadar, Elastic and others. If you have already invested in a platform, the engagement starts by making it work rather than replacing it.
Illustrative. Scenarios drawn from common engagement patterns.
A SIEM nobody reads any more
No out-of-hours coverage at all
A security team spending its time on triage
The first hours decide what you can prove.
When an incident becomes a notification, a claim or a case, the standard changes: what you believe happened stops mattering and what you can evidence starts to. Gryffin's DFIR practice combines containment speed with forensic rigour - acquiring evidence properly from the first hour, reconstructing what actually occurred, and reporting it to a standard that survives challenge.
What the engagement covers.
Emergency response and containment
Rapid engagement to stop active intrusion - isolation, credential revocation and access closure - executed so that evidence is preserved rather than destroyed.
Forensic acquisition
Sound acquisition across endpoints, servers, mobile devices, cloud control planes and SaaS audit logs, under documented chain of custody.
Timeline reconstruction
Establishing initial access, dwell time, lateral movement, privilege use and actions on objectives from the evidence.
Data exposure scoping
Determining what data was actually accessed rather than merely accessible - the distinction on which most notification decisions turn.
Malware and artefact analysis
Analysis of tooling, persistence and command-and-control infrastructure, producing indicators for detection and hunting.
Reporting and expert support
Findings documented to evidentiary standards, with expert explanation and testimony support for regulatory, insurance or legal proceedings.
What you receive
Containment without destroying evidence
Rebuilding a compromised host is the fastest way to lose the answer. Our responders contain and preserve simultaneously, because the notification question arrives a week later and needs evidence.
Cloud and SaaS acquisition, not just disks
Investigations now run through cloud control planes, identity logs and collaboration platforms. Our acquisition capability covers them alongside traditional endpoints and mobile devices.
Structured with your counsel
Scope, privilege, disclosure obligations and reporting standard are agreed with your legal advisors before collection begins.
Confidence stated honestly
Reports separate what the evidence establishes from what it suggests. Overstated forensic findings collapse under cross-examination, and we will not write them.
Illustrative. Scenarios drawn from common engagement patterns.

An incident that looked contained but was not
Attack it properly, or find out the hard way.
A penetration test is only worth what its findings are worth. Automated scanning tells you which software versions are old; it does not tell you that a low-privilege user can read another customer's records by changing one identifier. Gryffin's testing combines tooling for coverage with manual, business-logic-aware testing for the findings that actually matter - then reports them in a form your engineers can act on the same week.
What the engagement covers.
External infrastructure testing
Internet-facing assets, exposed services, misconfiguration, weak transport security and credential exposure - assessed the way an unauthenticated attacker would approach them.
Internal network testing
Assumed-breach testing from inside the network: privilege escalation, lateral movement, Active Directory attack paths, credential harvesting and access to crown-jewel systems.
Web application testing
Manual testing against the OWASP ASVS covering authorisation, session handling, injection, business-logic abuse and multi-tenant isolation, on top of automated coverage.
Mobile application testing
iOS and Android assessment across client-side storage, transport security, platform misuse, anti-tampering, and the backend APIs the app depends on, aligned to OWASP MASVS.
API testing
REST, GraphQL and service-to-service interfaces assessed against the OWASP API Top 10 - broken object-level authorisation, excessive data exposure, rate-limit bypass, token and key handling.
Cloud configuration review
Authenticated review of cloud accounts covering identity policy, network exposure, storage permissions, logging and key management.
What you receive
Certified testers, recognised methodology
Testing follows PTES, OWASP ASVS, MASVS and the API Top 10, mapped to MITRE ATT&CK, delivered by testers holding OSCP, CREST and equivalent credentials - so the report holds up in customer security reviews and regulatory scrutiny.
Manual depth where it counts
Roughly the majority of the findings we consider high severity come from manual testing of authorisation and business logic. Those are the flaws no scanner reports and no attacker ignores.
Retest included, not sold separately
Remediation verification is part of the engagement. You get an updated report showing findings closed, which is usually what the customer or auditor actually asked for.
Production-safe rules of engagement
Scope, timing, rate limits, prohibited actions and abort conditions are agreed and signed before testing begins, with a named contact reachable throughout.
Illustrative. Scenarios drawn from common engagement patterns.

Detect it early. Recover without paying.
Ransomware is not a single event; it is a campaign with a long, noisy run-up - initial access, credential theft, lateral movement, backup tampering - and only then encryption. Every stage before the last is an opportunity to detect and stop it. Gryffin builds detection across that whole chain, hardens the backups attackers go after first, and tests recovery so the decision about paying never has to be a real one.
What the engagement covers.
Precursor detection
Detection content for the stages that precede encryption: credential dumping, privilege escalation, lateral movement, shadow copy deletion and backup tampering.
Encryption behaviour detection and automated containment
Behavioural detection of mass file modification with automated host isolation, executed within seconds rather than after triage.
Backup immutability and isolation
Review and hardening of backup architecture - immutable copies, isolated credentials, offline or logically air-gapped tiers - because attackers target backups before they encrypt.
Recovery runbooks and testing
Documented recovery procedures with defined recovery objectives, tested against real restore timings rather than assumed ones.
Attack surface reduction
Closing the common initial access routes: exposed remote access, unpatched perimeter services, weak authentication and over-permissive privilege.
Retained incident response
A contracted response capability with committed activation times and pre-authorised containment actions.
What you receive
Detection across the whole chain
Detecting encryption is detecting failure. Our content covers the days of activity that precede it, where stopping the campaign is still cheap.
Backups hardened as a target
Modern ransomware operators find and destroy backups first. We review backup architecture the way an attacker would and harden the paths they use.
Recovery times measured, not estimated
Restore procedures are tested against real data volumes. Organisations routinely discover their assumed recovery time is out by an order of magnitude - better to find that in a test.
Containment that does not wait for approval
Automated isolation on encryption behaviour, under authority agreed in advance. Minutes of delay is the difference between one host and the estate.
