CYBERSECURITY CONSULTING
Build capability, not dependency.
Izerone helps organisations improve how they hunt, detect and respond to threats. The aim is not to sell contractor days. It is to leave you with stronger methods, better decisions and a capability your own people can run.
Five lines. The capability is knowing which question to ask — and that is the part I hand over.

Four ways Izerone can help
Threat hunting is the flagship. Detection & SOC and incident response extend the same security capability; Cyber Essentials provides a practical entry point for smaller UK organisations.
Threat Hunting
Build or mature a repeatable, intelligence-led and hypothesis-driven hunting capability.
Explore threat hunting → 02Detection & SOC
Improve detection engineering, coverage, SOC processes and operational effectiveness.
Explore detection & SOC → 03Incident Response
Investigate, contain and learn from incidents, with specialist technical delivery where required.
Explore incident response → 04Cyber Essentials
Practical preparation and advisory for UK organisations seeking certification and stronger foundations.

Bringing someone in to run hunts can get you findings. It does not necessarily leave you with a team that can find the same things next quarter. Izerone focuses on the capability, operating model and knowledge that remain after the engagement.
Building the capability gets you a function: documented hypotheses, playbooks anyone can pick up, a cadence that holds during a busy month, and findings that feed back into detection rather than sitting in a report. The engagement ends. The capability does not.
If what you need right now is findings rather than a function, say so. A scoped proof-of-concept hunt is often the honest first step, and sometimes the only step you need.
What a capability actually consists of
“Capability” is a word consultants use to avoid being specific. Here is what gets delivered.
- Methodology — intelligence-led and hypothesis-driven hunting, mapped to MITRE ATT&CK, adapted to your threat profile rather than a generic template
- Reusable playbooks — documented hunts that produce the same quality of result regardless of who runs them
- Operating procedures and governance — who hunts, how often, who reviews it, and what happens to what is found
- Reporting — executive and technical output that makes the function legible to the people who fund it
- A feedback loop — findings that become detections, so the same gap is not hunted twice
- Developed analysts — a team mentored to a consistent standard, which is the part that determines whether any of the above survives
Most teams are at Level 1 and do not know it
The Hunting Maturity Model gives you a way to say where you actually are. Level 0 is alert handling with no hunting at all. Level 1 is collecting good telemetry and occasionally searching it. Level 2 is following hunting procedures that other people wrote, consistently, and turning what you find into detections. Above that, Level 3 is a team writing its own, and Level 4 is automating the ones that repeat.
Getting up the ladder is less about tooling than most vendors suggest. It needs documented procedures, reusable playbooks, a governance rhythm, and someone senior enough to insist the findings turn into something. I have taken a CNI capability along exactly that path, and led the team that runs it.
Ways to work together
Consulting engagements, scoped to where you are rather than sold as a package.
Capability assessment
An honest read of where your hunting sits today against the Hunting Maturity Model — based on what your team actually does, not what the policy says. Delivered with a prioritised route to where you want to be.
Capability build
The main engagement. Methodology, reusable playbooks, operating procedures, governance and reporting — the structure that turns occasional searching into a function that runs to a schedule and survives people leaving.
Team development and mentoring
Working alongside your analysts on live hunts, with review and quality assurance, until they are running them independently and to a consistent standard. Capability lives in people, not documents.
Proof-of-concept hunt
A short, scoped hunt against agreed hypotheses. Useful where you need evidence that hunting will find something in your estate before committing to building the function.
Advisory retainer
Ongoing steer as the capability matures — reviewing hunt output, assuring quality, shaping the next stage. Advisory rather than delivery, sized to a few days a month.
Who this is for
Security leaders who have the telemetry and the people, but no structured hunting function — and who would rather own the capability than rent the activity. Typically a head of security, SOC manager, or a team currently reliant on an MSSP for everything beyond alert triage.
Smaller organisations usually need foundations before they need hunting. If you are a micro or small business, Cyber Essentials is the more useful place to start — and I can help with that too.
IT and OT are not the same problem
In utilities, manufacturing, energy and transport, the interesting risk sits where corporate IT meets operational technology. A hunting capability built only for the IT estate stops at exactly the boundary that matters, and you cannot simply deploy an agent onto a process network.
My first qualification was in instrumentation engineering — control systems, electronics and industrial process. That is an unusual starting point for a threat hunter, and it is the reason IT/OT convergence work is something I take on rather than avoid.
Who you would be working with
Izerone Solutions is led by Shrinivas Yerramshetty, a senior cybersecurity practitioner with a career in IT going back to 1997. The background spans enterprise UNIX and Solaris engineering, cybersecurity, incident response, SOC and threat hunting in UK critical national infrastructure. That is why the hunting starts from how a system is supposed to behave, rather than from a threat feed.
- Established and led a dedicated threat hunting team in a CNI environment, from nothing to a governed, repeatable capability
- Hands-on across Microsoft Defender, IBM QRadar, Splunk and ArcSight
- IASME Cyber Essentials Assessor and IASME Cyber Assurance Assessor (2025)
- Instrumentation engineering background, giving a working understanding of OT environments
Start with a conversation, not a proposal
Tell me what you are running and what is worrying you. If I am not the right fit I will say so, and point you at what is.
