01 / CLEAR RESPONSIBILITYFor technology leaders, IT teams and procurement
Security needs people.
People need
clear ownership.
Know what your security provider owns, what stays with your team and how the agreed work will be measured.
A useful managed service begins with an operating decision: what needs to improve, who can act and what evidence will show progress. We help turn those decisions into a clear scope.
Build around your internal team, MSP and existing security tools. Address gaps in cloud configuration, identity, monitoring handoffs and incident readiness with explicitly agreed workstreams.
Explore the service model02 / THE RIGHT WORKSTREAMS
Your platforms. A defined service.
Google Workspace security
Define the controls and administrative routines protecting Workspace accounts, sharing and connected applications.
AWS security assessment & hardening
Connect account structure, workload identities, exposure and security evidence to a manageable improvement plan.
Azure & Google Cloud security
Specify platform configuration, workload identity and logging work across your selected Azure or Google Cloud environments.
Identity & endpoint security programme
Bring privileged access, endpoint ownership and administrative practice into one accountable improvement programme.
Security monitoring & SOC operating model
Define log coverage, triage ownership, escalation and response authority before buying or extending a monitoring service.
Incident response readiness & retainer
Prepare the authority, access, contacts and commercial arrangements required to mobilise incident-response support.
Virtual CISO & security leadership
Establish security ownership, a prioritised programme and a reporting rhythm that fits your management team.
Assessment & compliance readiness
Determine the relevant baseline and evidence gaps before commissioning changes or making assurance claims.
Penetration testing & vulnerability assessment
Use a defined technical assessment to validate important boundaries and verify selected remediation outcomes.
From your environment
to a considered proposal.
01
Describe your platforms
Microsoft 365, Google Workspace, AWS, Azure, Google Cloud or on-premises systems.
02
Identify the support gap
Hardening, monitoring, response readiness, leadership or assurance.
03
Review the proposed fit
The RFP tool explains relevant services and the inputs needed to scope them.
04
Agree the operating model
Confirm coverage, ownership, access, licences, data handling and acceptance.
05
Onboard and improve
Introduce agreed changes and review service evidence against the contract.
MONITORING & RESPONSEDefine the requirements
Coverage means
more than
a dashboard.
Logs need an owner. Incidents need authority to act.
Specify operating hours, alert sources, escalation paths and containment decisions. Describe your existing SOC or provider so the proposal addresses actual gaps.
Monitoring delivery, staffing and incident-response retainer terms require confirmation. A request for 24/7 coverage is a requirement to evaluate, not an activated service.
