Disaster recovery testing: can your investment firm resume critical work?

A disaster recovery plan can look complete on paper and still fail when a real disruption arrives. For investment firms, the real test is whether people can keep critical work moving when a system, supplier, location or dataset becomes unavailable. That may mean restoring trading access, protecting an active transaction, recovering investor reporting, or keeping secure communications available during a high-pressure period.

That question matters because uptime, confidentiality and accurate information can directly affect trading, deal execution, portfolio oversight and investor communications. Alternit One’s work with investment-focused organisations reflects those pressures: disaster recovery should be tested as a business capability, not a technical checklist that ends when an application comes back online.

Recovery priorities differ across investment firms

A hedge fund may need secure access to trading platforms, market-data feeds and communications within minutes. A private equity firm may be in the middle of a transaction and need controlled access to deal rooms, models and investor material. Venture capital teams often depend on cloud identity, collaboration and SaaS availability. Family offices may prioritise privacy, trusted communications and discreet access to sensitive records. Each firm should identify which business services must return first and which technology, people and third parties they depend on.

Table 1. Recovery priorities across investment firms

Firm type	Recovery priority	Example dependency
Hedge funds	Maintain access to trading, market data and secure communications.	Identity, market-data feeds, connectivity and cloud applications.
Private equity	Protect deal execution, portfolio oversight and investor reporting.	Deal rooms, collaboration platforms, finance data and access controls.
Venture capital	Keep distributed teams collaborating securely across locations.	Cloud identity, SaaS collaboration, devices and internet connectivity.
Family offices	Preserve discreet, trusted access to sensitive records and communications.	Identity, secure communications, document platforms and backup services.

A useful DR programme therefore starts with business services, not servers. It maps the technology, people, data, facilities and third parties needed to deliver those services, then tests what happens when one or more dependencies fail.

What should a meaningful DR test prove?

For FCA-regulated firms that are in scope of the operational resilience rules, scenario testing should demonstrate that important business services can remain within defined impact tolerances through severe but plausible disruption. The FCA’s 2026 observations also emphasise broader mapping, third-party resilience, clear testing methodology and evidence that boards can understand and challenge.

That does not mean every exercise needs to be a full production failover. A mature testing cycle can move from tabletop walkthroughs to representative data restores, identity recovery, application failover and eventually end-to-end service testing. The NCSC similarly recommends practical exercises, testing with suppliers, validating workarounds and measuring how long alternative processes remain sustainable.

Table 2. What a DR test should validate

Test area	What to validate	Evidence to retain
Business service	End-to-end recovery, including people and third parties.	Actual recovery time, service status and unresolved dependencies.
Data and backups	Representative restores, integrity checks and usable recovery points.	Restore logs, validation results and recovery-point evidence.
Identity and access	Authorised users can regain secure access if primary services fail.	Access test results, privileged-access checks and exceptions.
Applications and connectivity	Critical applications can fail over or be restored with required network paths.	Failover timings, connectivity checks and application validation.
Communications and workarounds	Teams can coordinate internally, externally and with suppliers.	Exercise records, contact tests, workaround duration and lessons learned.

The evidence matters as much as the recovery

A successful test should leave more than a green status. Record the scenario, business services affected, expected objectives, actual recovery times, recovery-point results, communications, supplier involvement, manual workarounds, exceptions and decisions made under pressure. Where something takes longer than expected, assign an owner and target date, then retest after remediation.

Recovery time objectives can be misleading if used alone. Restoring an application does not necessarily mean the investment service is operating normally. Teams may still need to reconcile data, validate access, contact investors or rebuild dependent workflows. Recovery should be measured from the perspective of the critical work the firm needs to deliver, not only when infrastructure becomes available.

Make disaster recovery a business exercise

The strongest DR tests bring technology, operations, compliance, leadership and key suppliers into the same exercise. That makes the outcome more realistic and exposes assumptions technical testing can miss, including unclear decision rights, supplier dependencies or manual processes that cannot operate for as long as expected.

For investment firms, the practical question is simple: if disruption happened during a critical trading, deal, reporting or investor-servicing period, could the firm restore the work that matters before the impact became unacceptable? Regular, evidence-led testing gives leadership a clearer answer and shows where cloud infrastructure, cybersecurity, identity or backup improvements are needed before a real incident.
