The automation shift: how aerospace & defense teams rebuilt attestations for scale and accuracy with CoreStream GRC
In aerospace and defense, assurance often breaks in a predictable place: the evidence trail. Not because of the teams, but because manual attestations create evidence debt. Often, you only feel it when audit season hits, or when leadership asks for proof across a complex footprint and you realize the “truth” lives scattered across spreadsheets and inboxes.
These anonymized marine, defense, and aerospace clients we worked with, are a great example that shows what changed when a global team moved from manual surveys and Excel reporting to a repeatable workflow using CoreStream GRC, turning assurance into something they could run, not constantly rebuild.
Client profile snapshot (anonymized)
- Sector: marine, defense, and aerospace
- Footprint: multi-entity, multi-jurisdiction (including; the EU, UK, Africa, Asia and the Americas.)
- Number of employees: 2,500+ employees worldwide
- Audience: all global senior employees participating in recurring attestations to key policies and procedures
Before: surveys and spreadsheets could not scale
Before CoreStream GRC these clients’ programs relied on manual surveys with results captured and reported in Excel. Consolidation was time-consuming, executive dashboards were not possible, and inputs varied across business units and jurisdictions.
Even though it was slow, it was justified because ‘it worked’. Until it didn’t.
- Chasing completions became the process.
- Every attestation owner and control owner answered differently, so the risk and compliance data did not line up, without heavy human interpretation and verification.
- Leadership reporting meant days of consolidation and spreadsheet manipulation
- Version control was weak, audit trails were patchy
- Leaders got point-in-time packs, not real visibility into the assurance cycle
As Michael Rasmussen, GRC 20/20 pundit, explains using a driving analogy:
“If you’re always looking back, you crash.”
In other words, organizations stuck in old spreadsheets are reacting, not anticipating.
These clients illustrate exactly how spreadsheet-led governance feels fine in calm periods, then collapses under scrutiny.
The ICAEW cites commonly referenced research suggesting up to 90% of spreadsheets contain errors.
This becomes a real problem in high stakes environments. Spreadsheets cannot be used as an entire control system, when they are made to function as a calculator.
The breaking point : senior leadership wanted answers, not archaeology
Leadership needed a way to run assurance on their risk and compliance requirements they could trust without a rebuild:
- standardized capture
- clean progress tracking
- consistent outputs
- real-time visibility through dashboards
At this point, “better spreadsheets” or “more spreadsheets” is not a plan. You need purpose built compliance management software that can produce defensible reporting and a clean trail for audit management software and internal audit software needs.
After: attestations became a proactive and streamlined workflow, not a manual scramble
- CoreStream GRC implemented an online Management Assurance solution and automated the assurance cycle.
What the workflow included;
- Management Assurance survey cycles run 4 times per year
- Automated alerts to management linking directly to the survey requirement
- Intelligent branch-logic forms where question sets adjust based on prior answers and user properties
- Responses routed through a consistent review workflow
- Corrective actions generated based on responses
- Executive reporting on progress and outcomes using role-based drillable dashboards
- This is large-scale compliance automation in the only way that matters: the evidence trail is created as work happens, not reconstructed later.
What changed on the ground: repeatable, reliable risk and compliance assurance
Once the program ran inside one system:
- manual consolidation and chasing dropped sharply
- embedded guidance reduced end-user support needs
- leadership could see live completion and outcomes, not last month’s snapshot
- corrective actions were created and tracked to closure, not lost in follow-up threads
- teams could trend response rates and outcomes over time, then feed that into training and change work
For risk teams, that matters because assurance results stop being vague updates and start becoming structured signals you can use inside an enterprise risk management software program or risk assessment software workflow.
The CoreStream GRC recommendations: 5 lessons aerospace and defense teams can steal
1) Standardize the input or the output is meaningless
If every entity answers in a different format, you cannot compare risk or spot gaps.
2) Build corrective action into the attestation itself
If actions live outside the process, closure depends on memory. Linking actions to responses makes accountability real.
3) Treat review as part of assurance, not an afterthought
Routing, sign-off, and comments need to be captured in-system, or you are back to email archaeology.
4) Make evidence exportable, not hunted
Audit questions are predictable. You should be able to show what was asked, who responded, who reviewed, what changed, and what was done about it.
5) Use cadence to create rhythm
Quarterly or multi-cycle attestations reduce the panic cycle and make assurance an operating habit, not a one-off event.
Our takeaway
The big takeaway is simple. In aerospace and defense, attestations are not the hard part. Defensible assurance is.
When the process runs on spreadsheets, you can usually get the answers, but you cannot get them fast, consistently or with a clean audit trail. When attestations run as a workflow, evidence becomes automatic, corrective actions stop stalling, and leadership gets real visibility across the full footprint.
If your team is still rebuilding proof at the end of every cycle, you are not running assurance. You are paying down evidence debt.

FAQ on CoreStream GRC and aerospace and defense teams
Automated attestations are a structured way to collect policy, control, and compliance confirmations through workflows instead of spreadsheets and email. In aerospace and defense, this usually means recurring certification cycles with built-in review, audit trails, and corrective actions so assurance is repeatable and defensible.
They fail when evidence is scattered across spreadsheets, inboxes, and disconnected tools. Teams end up chasing completions, reconciling inconsistent inputs, and rebuilding reporting each cycle. The result is slower assurance, weaker audit trails, and less confidence in the data.
Audit management software and internal audit software depend on evidence: what was asked, who responded, who reviewed, what changed, and what actions followed. Automated attestations create that trail automatically, so audits stop being a scramble to rebuild proof.
Point-in-time reporting is a snapshot built after the fact, usually through manual consolidation. Real-time dashboards show live completion, outcomes, and action status as the cycle runs. For leadership, that changes assurance from retrospective reporting to active oversight.
It depends on risk, regulators, and operating model, but many teams move toward quarterly or multi-cycle attestations for higher-risk areas. The key is rhythm. A consistent cadence reduces panic reporting and makes assurance part of day-to-day governance.
CoreStream GRC helps teams run attestations as a connected workflow, with recurring cycles, automated notifications, intelligent forms, review and sign-off, corrective actions, and role-based dashboards. The result is a clearer audit trail and less manual effort spent rebuilding evidence at the end of each cycle.
