Cybersecurity risk assessment: what financial firms should review
Updated: 11 minutes ago
A single weak link, an unpatched laptop, an over-permissioned account, a supplier with sloppy access controls, is often all it takes to expose sensitive financial data.
According to IBM's 2026 Cost of a Data Breach Report, the average breach at a financial services firm now costs approximately $6.29 million. Verizon's 2025 Data Breach Investigations Report analysed more than 22,000 security incidents and found credential abuse behind 22% of breaches and vulnerability exploitation behind another 20%.
The firms that avoid becoming a statistic aren't the ones with the biggest security budgets. They're the ones that review their risk regularly and act on what they find.

.
Know what you're protecting
Everything starts with visibility. You can't secure what you haven't mapped.
Firms should identify and track:
Client and investor information
Financial and transaction records
Authentication credentials
Investment information
Regulatory documents
Internal business data
For each category, know where it's stored, who can access it, and how it moves across your systems. This is the foundation everything else builds on.
Lock down access and endpoints
Most breaches don't start with a sophisticated exploit. They start with an account or device that should never have had access in the first place.
User access. Review permissions, privileged accounts, and remote access paths. Specifically check:
Multi-factor authentication coverage
Password policies
Dormant accounts
Administrative privileges
Joiner, mover, and leaver processes
Removing access nobody needs shrinks your attack surface immediately, and it's often the cheapest fix on this list.
Endpoints. Laptops, desktops, and mobile devices are common entry points. Review endpoint protection, encryption, patching cadence, and device access controls. Ongoing monitoring helps catch suspicious activity before it spreads.
Secure the infrastructure
Network security. Assess firewalls, network segmentation, VPNs, and remote access controls, and keep every exposed system patched. This matters more than ever: Verizon's 2025 report found vulnerability exploitation up 34% year over year, meaning unpatched systems are an increasingly common way in.
Cloud security. Cloud platforms power much of modern financial operations, but misconfiguration is one of the most common ways firms expose data by accident. Review permissions, authentication, data-sharing settings, and administrative controls across every cloud platform in use.
Manage third-party and human risk
Third-party risk. Most financial firms rely on external providers for some part of their operations, and each one is a potential doorway into your systems. This risk is growing fast: Verizon's 2025 report found third-party involvement in breaches doubled to 30% year over year. Review what data and system access every vendor actually has, not just what they're supposed to have.
Employee security. Employees handle sensitive systems daily, which makes human error and compromised credentials an ongoing risk rather than a one-time fix. Assess security awareness, phishing resilience, and how quickly staff report suspicious activity. Regular training keeps this sharp.
Prepare for when, not if
Incident response. Test how your organisation would actually respond to:
Ransomware
Phishing attacks
Compromised accounts
Data theft
Malware
Third-party incidents
Tabletop exercises reveal gaps in responsibility, communication, and escalation before a real incident does.
Backup and recovery. Reliable backups are what turn a serious incident into a manageable one. Review backup frequency, protection, and restoration testing. A backup you haven't tested restoring is a backup you can't rely on.
Compliance. Financial firms operate under strict regulatory requirements. Review the assessment against applicable regulations and internal policy, and document both the findings and the remediation. That documentation is your evidence of active risk management if a regulator ever asks.
Turn findings into action
An assessment is only useful if it leads to change. Prioritise findings by impact and likelihood:
Priority | Action |
Critical | Act immediately |
High | Address promptly |
Medium | Add to the security roadmap |
Low | Monitor and resolve as needed |
Strengthen your financial cybersecurity
A regular cybersecurity risk assessment gives financial firms a clear, current picture of where they're exposed, and a prioritised path to closing those gaps. Reviewing data, access, infrastructure, third parties, people, and recovery plans together is what turns a checklist into real resilience.
