Vendor-agnostic advisory. Solution-driven execution. Measurable risk reduction.
My engagement model focuses on solving business and technical challenges across four phases: Assess risks & architecture, Design target solutions, Implement controls & automation, and Optimise operations with executive reporting.
Plan and execute SIEM migrations from Microsoft Sentinel, Splunk, QRadar, or mixed logging estates into Google SecOps or modern target architectures for enterprise organisations.
Design, optimise, and operationalise Google SecOps with Chronicle SIEM-SOAR, AIOps triage, threat hunting, UEBA, Retrohunt, and security operations workflows for enterprise security teams.
Build secure multi-cloud foundations across AWS, Azure, and GCP using Wiz, Tenable, CSPM, CWPP, and DSPM platforms to eliminate IAM drift, secure Kubernetes fleets, and harden platform infrastructure.
Provide executive security and IT operational leadership, board reporting, roadmap ownership, and programme oversight for mid-sized and enterprise organisations.
Support ISO 27001, NIST CSF 2.0, DORA, GDPR, and PCI-aligned security & IT resilience programmes with control mapping, policy improvement, and audit readiness for organisations.
Implement Data Security Posture Management (DSPM), DLP policies, alerting, data classification, and monitoring for collaboration, endpoint, and cloud environments across enterprise teams.
Improve detections, alert quality, AIOps triage, enrichment, and automated SOAR workflows to make security operations more effective and scalable for enterprise SOCs.
Harden cloud and hybrid IT platform infrastructure with security reviews for identity, Zero Trust SASE, endpoints, logging, network controls, containers, and CI/CD in enterprise environments.
Use Terraform, OpenTofu, Ansible, PowerShell, and Cloud FinOps automation patterns to reduce manual effort, control cloud costs, and improve IT consistency for enterprise clients.
Design and optimise endpoint fleet and identity architectures with Entra ID, Okta, CrowdStrike, SentinelOne, and Defender coverage across Windows, macOS, and Linux fleets.
Implement Software Bill of Materials (SBOM) enforcement, SLSA provenance, CI/CD pipeline hardening, secret scanning, and container runtime security for modern engineering teams.
Security reviews and risk governance for GenAI applications, RAG pipelines, LLM prompt injection defenses, Data Leakage Prevention (DLP), and UK AI Safety Institute / EU AI Act compliance alignment.
Estimate potential annual licensing savings and migration duration when switching from your current SIEM platform to Google SecOps.
Migrated 1.2PB of daily log volume from Microsoft Sentinel to Google SecOps across AWS, Azure, and on-premises infrastructure.
Achieved 87% improvement in cloud security compliance scores across AWS, Azure, and GCP through IaC guardrails and posture automation.
Provided fractional vCISO support leading to successful Series B funding and ISO 27001 certification for a fintech.
Automated multi-cloud infrastructure provisioning and established real-time FinOps cost governance across AWS & Azure.
Migrated 28 hospital facilities and 14,000 endpoint devices from legacy VPNs to Zero Trust ZTNA & Okta PAM.
Secured customer-facing AI agents, LLM RAG pipelines, and AI-assisted code repositories against prompt injection and PII leakage.
A structured, risk-prioritised 4-phase framework designed to deliver measurable IT operations and security transformation without operational disruption.
Comprehensive review of current IT logging estates, cloud posture across AWS/Azure/GCP, identity controls, and operational bottlenecks.
Definition of target architecture, canonical data models for Google SecOps, automated IaC guardrails, and executive roadmap alignment.
Phased migration of log sources, detection rules, and platform hardening with parallel-run validation and 100% parity guarantees.
AIOps triage automation, Cloud FinOps cost control, continuous threat hunting, and board-level security posture reporting.

“Muzammil delivered our SIEM migration from Sentinel to Google SecOps without a single dropped alert or downtime. Log ingestion costs dropped by 35% while our SOC alert triage speed tripled.”
“The multi-cloud security architecture and IaC guardrails transformed our engineering culture. We remediated 15 critical risks within 4 months with zero deployment friction.”
“As our vCISO, Muzammil brought clear executive governance and board-level clarity that allowed us to complete Series B funding with zero security due diligence blockers.”

Based in the UK, I work with enterprise clients across the UK, EU, and Middle East. Engagements can be delivered remotely or via hybrid on-site workshops for key architecture phases.
Engagements are structured as fixed-scope project milestones (e.g. 8-week SIEM migration blueprint) or monthly retainer models (e.g. fractional vCISO at 12-20 hrs/month).
Yes. Every engagement is designed to upskill and empower your in-house SOC and platform engineers, transferring knowledge and IaC codebase documentation directly to your staff.
We execute an 8-phase process: log volume audit, BindPlane collector setup, YARA-L detection rule conversion, UDM schema normalization, and a 90-day dual-run validation period.
Provides strategic security governance, risk assessment, ISO 27001 / SOC 2 readiness, and monthly board-level risk reporting without the overhead of a full-time executive hire.
You own 100% of all Terraform modules, Ansible playbooks, custom YARA-L rules, and architecture documentation created during the engagement.
