A cyber security audit gives organisations a clearer view of risks across their systems, users, devices and data. This article explores the common blind spots audits uncover, how findings can be prioritised into a practical improvement plan and why regular reviews support compliance, resilience, growth and stronger business assurance.
Understanding your cyber security risk
Many organisations have far less visibility into their cyber security risks than they think they do. When we carry out cyber security risk reviews (typically including Microsoft 365 reviews, CIS benchmark assessments, Cyber Essentials preparation, NIST assessments or security onboarding projects), we frequently find that organisations know they need to be secure but struggle to clearly answer key questions to understand the risk they face.
Some of the key questions we ask include:
- What vulnerabilities currently exist across the business?
- Who has privileged access to key systems?
- Is critical data properly protected and backed up?
- How exposed are you to phishing, ransomware or account compromises?
- Are security controls being monitored?
- What are your biggest cyber risks today versus six months ago?
The most common cyber security blind spots
The most common cyber security risks and blind spots aren’t usually the things organisations expect. They’re often everyday areas that have evolved over time without anyone taking a step back to review them properly and understand how they now present a risk to their business.
One recurring theme is that organisations often have security products in place but no single view of risk across the organisation. Another common blind spot is the assumption that purchasing security tools means cyber risk is under control.
The organisations that struggle most are often unable to answer basic questions: who has access to what, which data is shared externally, what devices connect to company systems and where their greatest risks lie.
A cyber security audit or structured review often provides the first genuinely clear, organisation-wide view of these risks.
How cyber security audits uncover hidden risks
For many organisations, a cyber security audit can help identify and uncover some of the key risks they are facing and is an effective first step in protecting their people, data, and key systems.
A cyber security audit looks far beyond the day-to-day management of IT systems. Day-to-day IT is often focused on keeping users productive, resolving issues and maintaining services. A cyber security audit takes a step back and asks a different question: how secure is the organisation, and what evidence do we have to support that?
A worthwhile audit typically reviews:
- identity and access management
- administrator privileges
- Microsoft 365 configuration
- email security
- endpoint protection
- patching, backups
- external sharing
- logging and alerting
- network security
- third-party applications
- incident response and governance
For Microsoft 365 environments, we place particular focus on Entra ID, Conditional Access, MFA, Exchange Online, SharePoint, OneDrive, Teams, Defender and Intune because weaknesses in these areas are often interconnected.
What makes an audit valuable is that it often reveals issues that aren’t visible through normal day-to-day IT operations. For example, we’ve seen organisations with good endpoint protection but limited visibility of email and cloud risks. And we’ve also worked with organisations pursuing Cyber Essentials while fundamental Microsoft 365 and Entra ID security still needed attention.
A thorough cyber security audit also highlights the gap between what an organisation believes is in place and what is configured, monitored and reviewed. For example, we sometimes find that security information exists across multiple systems, but there is no single view of risk, ownership or remediation priorities. These aren’t usually dramatic failures. More often, they’re the result of technology evolving faster than the governance and oversight an organisation has in place.
Cyber security audits and visibility across your IT environment
Visibility across the whole IT environment has now become far more important because the traditional network boundary has effectively disappeared.
A few years ago, most systems, data and users were protected behind a company firewall. Today, businesses operate across a much broader digital environment, including:
- Microsoft 365
- Cloud-based applications
- Mobile devices
- Home networks
- Third-party suppliers
- Remote locations
Data is also constantly moving between people, devices and services, which means cyber risk is no longer confined to a single office or server room.
The challenge here is that each new cloud platform, application, device or supplier introduces another potential route into the business. If organisations only have visibility of their network, but not their Microsoft 365 environment, endpoints, identities, external sharing or third-party integrations, they are effectively managing only part of the risk picture. And as security information often exists across multiple tools, there is often no single, understandable view of what’s happening across the wider estate.
Today, organisations are adopting more cloud services and flexible working practices, so their technology often grows faster than their governance model. New applications are introduced, permissions are granted, sharing is enabled, and devices are added, but nobody periodically steps back to assess the cumulative risk.
A cyber security audit helps bring all of those moving parts together into a single picture, making it easier to identify weaknesses that would otherwise remain hidden.
Common cyber security risks an audit can uncover
The most common issues we uncover during cyber security audits are rarely sophisticated attacks or zero-day vulnerabilities. More often, they’re gaps that have developed gradually over time as systems, users and cloud services have grown faster than the organisation’s governance and oversight.
Some of the most common findings include:
- Excessive administrator privileges and accounts that haven’t been reviewed for years.
- Inconsistent multi-factor authentication (MFA) and Conditional Access policies across Microsoft 365.
- Unmanaged or poorly managed devices accessing company data.
- Broad external sharing within SharePoint, OneDrive and Teams.
- Guest accounts and third-party applications with unnecessary permissions.
- Weak visibility of email and cloud-based security risks.
- Unclear backup coverage, recovery processes and ownership.
- Security recommendations that have been identified previously but never fully implemented.
The findings that tend to surprise organisations are often not technical at all. What catches them out is discovering that they can’t answer fundamental governance questions with confidence.
Prioritising risks after a cyber security audit
One of the biggest mistakes organisations make after a cyber security audit is trying to fix everything at once. In reality, the priority should be determined by business risk, not simply by the length of the findings report.
We generally recommend looking at three factors:
- How likely is the issue to be exploited?
- What would the impact be on the business if it were?
- How quickly and cost-effectively can it be remediated?
For example, weaknesses around administrator accounts, MFA, Conditional Access, external sharing, privileged access or backup and recovery capabilities would typically be prioritised because they can have a direct impact on operations, data security and ransomware resilience.
The best audits don’t just produce a list of technical findings. They provide a prioritised roadmap that separates immediate actions from medium and longer-term improvements, clearly identifies ownership and explains the business impact of each recommendation.
We find that leadership teams respond far better when findings are presented in terms of operational risk, compliance exposure, customer impact and business continuity rather than purely technical language.

Cyber security audits support wider business priorities
Regular cyber security audits are about much more than IT, data, and systems security. Done properly, they support several wider objectives that are increasingly important to organisations of all sizes.
- Compliance and governance: Firstly, they help with compliance and governance. Frameworks such as Cyber Essentials, CIS Benchmarks and NIST provide structure and ensure important areas aren’t overlooked. An audit gives the business evidence that risks have been assessed, controls have been reviewed, and improvements are being actively managed, rather than relying on assumptions.
- Cyber insurance: They also play an important role in cyber insurance. We’re seeing insurers ask increasingly detailed questions about MFA, backups, privileged access, monitoring and incident response. An audit helps organisations understand their actual position before completing insurance renewals and can identify areas that may need attention before becoming a problem.
- Customer and supplier requirements are another key driver. We regularly work with organisations that need to demonstrate security maturity as part of tenders, due diligence exercises and supplier assessments. An audit provides evidence that security controls are being governed and continually improved, which can be invaluable when competing for new business or satisfying customer requirements.
- Business continuity: From a business continuity perspective, audits often uncover weaknesses that could affect operations during an incident. This might include gaps in backup coverage, recovery processes, access controls, monitoring or device management. Identifying and addressing these issues before an incident occurs can significantly reduce the operational impact of cyber attacks, outages or human error.
- Growth: Perhaps most importantly, audits support growth. As organisations adopt Microsoft 365, cloud applications, AI tools, remote working and new business processes, the risk landscape changes constantly. We’ve found that technology often grows faster than governance, leaving businesses with increasing complexity but limited visibility. Regular audits help ensure that security remains aligned with the organisation’s growth plans rather than becoming a barrier to them.
- Creating organisational confidence: The real value is confidence. Not confidence based on hope, but confidence based on evidence. A good audit gives leaders and directors a clearer understanding of risk, provides a practical roadmap for improvement and demonstrates to customers, insurers, regulators and stakeholders that cyber security is being actively managed. Ultimately, that’s not just good security practice; it’s good business management.

When to review your cyber security position
Think of cyber security as an ongoing management discipline rather than an annual exercise. A formal audit might take place annually, but an organisation’s risk profile can change significantly throughout the year, particularly as new systems, suppliers, users and ways of working are introduced.
As a minimum, organisations should carry out a comprehensive review of their cyber security position annually, with regular reviews of key controls, risks and security reports throughout the year. The organisations that tend to stay ahead of risk are those that treat cyber security as a continuous improvement process rather than a one-off compliance exercise.
There are also several situations where we recommend carrying out a new audit rather than waiting for the next scheduled review. These include:
- A migration to Microsoft 365, Azure or other cloud services.
- A significant increase in remote or hybrid working.
- The introduction of AI platforms, third-party applications or new business systems.
- A merger, acquisition or business restructuring.
- Major network or infrastructure changes.
- Achieving or renewing Cyber Essentials, Cyber Essentials Plus or other certifications.
- Preparing for cyber insurance renewal or large customer due diligence exercises.
- Following a cyber incident, suspicious activity or security breach.
We also see organisations outgrow their original security model. What worked for a 20-person business often isn’t sufficient for a 100-person business operating multiple sites, cloud platforms and remote teams. Technology, processes and access permissions naturally evolve, which means the security position can drift over time if it isn’t reviewed regularly. This is something we encounter frequently in Microsoft 365 security reviews, where environments have grown organically, and nobody has stepped back to assess the cumulative impact of those changes.
Perhaps the biggest trigger is when leadership loses confidence in the answers they’re receiving. If a director asks simple questions such as “Who has access to our critical data?”, “Are our backups recoverable?” or “Are we secure?” and receives uncertain or conflicting responses, that’s usually a strong indication that a fresh audit is needed.
