Connect cyber requirements, controls, evidence, risks, and customer assurance
From cyber requirement to evidence-backed customer assurance.
STREAM® Cloud helps defence contractors connect cyber obligations, controls, assets, environments, evidence, exceptions, actions, residual risk decisions and assurance updates in one configurable workspace.
The defence cyber assurance challenge
Cyber risk assessments become stale as assets, users, vulnerabilities, incidents and supplier dependencies change. Control evidence and customer assurance packs are often fragmented across spreadsheets, tools, tickets, folders and individual owners — and customer obligations and framework controls are hard to trace to current evidence and follow-up actions.
Control owner attestations, evidence reviews and remediation follow-up are difficult to co-ordinate at pace. Defence contractors need customer-ready views for bids, renewals, accreditation / authorisation reviews, audits and public-sector assurance checks — built from the same underlying records, not rebuilt from scratch each time.
Access governance evidence such as joiner / mover / leaver, access reviews and privileged access recertification often lives in IAM tools, tickets, exports and email. Supplier and subcontractor evidence may not be linked to the customer obligations it supports, and accepted risks, exceptions, compensating controls and expiry dates can drift without visible follow-through.
What evidence-backed cyber assurance looks like
Moving from scattered control evidence and customer packs to evidence-backed cyber assurance is about requirement-to-control mapping, owner attestation, evidence freshness and a current view of posture and exceptions.
Requirement-to-control mapping
Contract security obligations, framework controls and customer-specific requirements held as linked records, traceable to the controls that meet them.
Evidence freshness and sufficiency
Control evidence captured against the obligations and controls it supports, with visible evidence status, freshness and sufficiency rather than scattered files.
Control owner attestation
Named control owners, attestation cycles and evidence reviews co-ordinated in one place — not chased through email, tickets and spreadsheets.
Current risk posture and residual risk
Current risk posture, residual risk, risk acceptances and compensating controls held alongside the evidence and actions behind them.
Exceptions, POA&M and remediation
Exceptions with expiry dates, POA&M / remediation plans and follow-up actions tracked through to closure with audit history.
Operational security evidence
JML, access reviews, privileged access recertification and other operational security evidence linked to the obligations and controls they support.
Supplier and subcontractor assurance
Supplier and subcontractor evidence connected to the customer obligations it underpins — not held in isolation from the contracts they relate to.
Customer assurance packs
Customer-ready views for bids, renewals, accreditation reviews, audits and public-sector assurance reviews — built from the same underlying records.
How STREAM® Cloud helps
STREAM® Cloud gives defence cyber GRC, assurance and operations teams practical structure for the work behind customer assurance — structured records, linked registers, dashboards and an audit history of what has changed.
Configurable record types for cyber obligations, framework controls, control owners, attestations, evidence items, risks, exceptions, actions, suppliers and assurance items
Configurable fields, with mandatory fields where required, so each register captures what your cyber assurance, GRC and operations teams actually need
Linked records that connect contract security obligations and frameworks (such as NIST 800-53, NIST CSF, ISO 27001, Cyber Essentials, CIS Controls and MITRE ATT&CK-informed references) to the controls, evidence and actions that meet them
Search across structured data so teams can find the right obligation, control, evidence item, exception or action quickly
Dashboards and reports that update as data is entered, giving cyber GRC, assurance and programme leads a current view of posture and readiness
Exports for customer assurance packs, accreditation / authorisation submissions, public-sector assurance reviews, internal audit and leadership updates
Permissions and controlled visibility so cyber GRC, security operations, IAM, supplier assurance, programme delivery and audit teams see what is relevant to them
Audit history of changes to support oversight, scrutiny and assurance discipline
Action tracking with owners, due dates, status, blockers and evidence trails for remediation, exception expiry and attestation follow-through
A guided product walkthrough so teams can see how the model fits their cyber assurance operating environment
STREAM® Cloud works alongside SIEM, EDR, IAM, ITSM, vulnerability, supplier and document systems as a configurable cyber assurance, evidence and follow-through workspace. Evidence can be stored or referenced, depending on implementation.
