Is an up-to-date antivirus enough to protect your SME against business interruption? Not necessarily. The main security errors observed during IT audits are often everyday deviations: backups never tested, access too extensive or updates postponed. Taken in isolation, they sometimes seem minor. Combined, they can weaken your data and the continuity of your operations.
To act effectively, we must distinguish emergencies from improvements to be planned. An audit report may contain many recommendations without clearly specifying who should act or in what order. The challenge is to transform each observation into a concrete priority, with a person responsible, a deadline and follow-up.
In this article, you'll learn about the most common discrepancies, what they mean for an SMEs, and what actions to address first, from passwords to restoring backups. You will also see how to clarify the roles between management, internal team and service providers, while taking into account FADP and data sovereignty in Switzerland. This approach concerns companies in Geneva, Meyrin, Vernier, Eaux-Vives, Collogny, Grand-Lancy and Petit-Lancy, as well as those in Switzerland.
Key Points
- The main security errors observed during IT audits often concern access, updates, backups and messaging.
- Evaluate each finding according to its exposure, its impact on the activity and the technical dependencies before deciding on its processing order.
- Transform recommendations into assigned actions, with a manager, a deadline defined by your company and a follow-up status.
- Verify that backups can actually support the recovery of operations in the event of an incident.
- Integrate FADP and data sovereignty in Switzerland into your security approach, without considering the audit as a guarantee of compliance.

Security errors in IT audit: why they weaken SMEs
A security error is a gap between expected protections and actual company practices. This may be an account which retains rights after a change of function, equipment whose updates are postponed or a backup procedure which has never been verified. These findings do not mean that an incident will necessarily occur. They indicate where a failure could expose information, disrupt service, or make it difficult to resume operations.
An audit highlights these gaps and helps understand the risks in the context of your SME. It does not itself correct weaknesses and does not guarantee their disappearance. The measures must then be decided, assigned and monitored. The main security errors observed during IT audits therefore matter as much for their technical nature as for their possible consequences on daily work, data and your ability to serve your customers.
A security audit examines the protection of systems and information. An IT audit assesses the IT environment and management more broadly. A penetration test simulates access attempts to look for exploitable vulnerabilities.
What does an IT security audit reveal?
Depending on the scope chosen, the examination may focus on workstation and server configurations, accounts and their authorizations, access management procedures, backups or team practices. It depends on the systems and activities actually examined. For example, an audit limited to messaging alone does not allow us to conclude on the security of the entire network.
In an SME, a concrete observation could be an old account still active or a shared folder accessible to people who no longer need it. The audit documents the deviation and its context, but does not prove that an intrusion took place. To interpret a recommendation, check the affected systems and the business activity that could be affected.
Why a seemingly minor error deserves attention
Too much access can expose business documents or personal data to people who don't need them. The risk depends in particular on the type of information, account privileges and protections in place. A backup that has never been tested for restoration poses another problem: after a failure or attack, you may not be able to quickly recover the files needed for the job.
- Link each finding to the data and services involved.
- Check who has access, then remove those that are no longer needed.
- Confirm that backups can be restored and that data remains available to authorized individuals.
In Switzerland, FADP regulates the processing of personal data. Data sovereignty also deserves concrete attention: identify where data is hosted and who can access it, then evaluate these elements according to the needs of your business and the applicable rules. Data localization contributes to this analysis, without alone constituting proof of compliance.
The security errors most often revealed by an IT audit
The findings vary depending on the scope examined, the technical environment and the company's practices. There is therefore no universal list or classification valid for each SME. The main security errors observed during IT audits nevertheless fall into useful families: identities and access, updates, backups, messaging and governance. For each finding, examine the gap, the possible risk, and the first action that can reduce it.
Access, identities and team awareness
An audit can identify an account without multi-factor authentication when this protection is relevant, rights that are too broad or shared accounts that prevent actions from being clearly identified. Access retained after departure or a change of function also deserves to be checked. In an environment using Microsoft Entra ID P1, the examination may include the configured identity settings and access practices. The name of the license is not enough to establish the level of protection.
Access rights should be reviewed regularly as business roles and needs evolve. Start by comparing permissions with current responsibilities, then remove those that are no longer needed. For messaging, define a simple procedure for reporting suspicious emails and regularly remind teams how to recognize phishing.
Backups, updates and documentation
A backup that has not been restored does not demonstrate that the data can be recovered. Schedule a restoration test and record its results. There 3-2-1-1-0 rule summarizes a backup strategy: three copies, two media, one offsite copy, one immutable copy and zero errors detected during checks.
A system or software that is not patched may retain known vulnerabilities. Establish an inventory of equipment and applications, then specify who tracks and applies updates. Incomplete documentation, for example without an identified responsible person for a service or without a restoration procedure, complicates decisions in the event of an incident. Note responsibilities, dependencies, and recovery steps.
Messaging and governance: connecting observation to action
To make the recommendations actionable, formulate each observation operationally:
- Access: the rights of an old role are still active. The risk is unnecessary exposure. First step: review the authorizations.
- Updates: no patch tracking is defined. Vulnerabilities could remain unfixed. First step: assign responsibility for monitoring.
- Backups: restoration has never been tested. The recovery capacity remains to be verified. First step: plan and document a test.
- Messaging: It is not clear how to report a suspicious email. The reaction may be delayed. First measure: define a procedure and communicate it.
- Governance: roles or procedures are poorly documented. Coordination can be complicated. First measure: designate a person responsible for each action.
These examples are checkpoints, not results attributed to all SMEs. Their relevance depends on the systems and uses examined. To compare these findings to your IT environment, exchange with the Flux Group team on the priorities of your SME.
How to assess the seriousness of the findings of an IT audit?
An observation is not classified solely according to its technicality. To decide what to process first, relate it to the relevant systems and activities of your SME. What data or functions would be exposed? Which team would be affected? What would happen if the service became unavailable? The priority depends on the risk for the activity and the means necessary to reduce it.
Classify deviations according to risk for the activity
Use a qualitative grid to compare findings without giving them an artificially precise score. For each element, indicate what justifies your appreciation. A system used for invoicing, for example, may have a different business impact than a secondary tool, even if the two have a similar technical gap.
Exposure : is the gap accessible from the outside, limited to a station or linked to internal access?
Business impact : what data, functions, teams or customer relationships would be affected?
Ease of correction : Can the measure be applied directly or does it require validation and testing?
Dependencies : Does the fix affect Microsoft 365, workstations, network, backups or a business process?
Add two benchmarks to this reading: the sensitivity of the data and the effects of an interruption. If personal information is involved, also examine its location and associated access. Data sovereignty in Switzerland is part of the analysis, but location alone is not enough to establish compliance.
The FADP must be taken into account when processing personal data. In Geneva, LIPAD can also concern public institutions and private entities responsible for a public task. Its applicability depends on the status and activities of the organization. For official guidelines on data protection, see the information from Federal Data Protection Officer.
Distinguish technical correction and organizational response
Immediate measures respond to significant exposure or direct impact on an essential activity. They may consist of reducing a right that is too broad or correcting a configuration, after checking the possible effects. Other findings lend themselves to planned improvement, for example clarifying who validates access or formalizing a restoration procedure. Set deadlines according to your constraints, without applying a standard deadline to different contexts.
Spot dependencies before you act. An account change may affect Microsoft 365; an update may require testing on the workstations; A recovery sometimes depends on the network and backups. Note these links in your grid, then have the sequence validated by those responsible for systems and operations. This method helps classify the top security errors observed during IT audits according to their actual effect, rather than just their technical appearance. Flux Group supports SMEs with IT support, cybersecurity and the management of their infrastructures. Discuss the findings of your audit with Flux Group.
After the IT audit: transform errors into a correction plan
An audit becomes useful when its findings lead to verifiable actions. For each deviation, first validate the observed fact and the system concerned. Then assign an action, make the correction, retain evidence, and reassess the risk. This monitoring prevents a recommendation from remaining without responsibility or from a modification being considered complete without verification.
Build a realistic action plan for an SME
Divide the measures between priority corrections and improvements to be scheduled. The first respond to a risk deemed significant for an activity or sensitive data. Seconds can be scheduled based on resources, technical dependencies and current operations. Have this order validated by the relevant business and IT managers so that decisions take into account protection and daily operation.
A follow-up plan can be kept simple. For each action, record:
- the finding and the system concerned;
- the expected action and the person responsible;
- the deadline decided by the company and the state of progress;
- the proof that will allow verification of the correction;
- temporary exceptions, their justification and the accepted residual risk.
This traceability clarifies the responsibilities between management, internal team and service provider. It also allows an exception to be re-examined when the context changes, rather than allowing it to become a permanent practice. Key security errors observed during IT audits should be tracked until resolved or a documented decision on remaining risk.
Check for fixes and maintain security
Define the expected proof before closing an action. For a configuration setting, this may be a documented verification of the setting. For a backup, keep the result of a test restore. For a procedure, check that it designates those responsible and that it can be applied by the people concerned. A capture or a note is not always enough: the evidence must correspond to the objective of the measurement.
After a significant change in the IT environment, reassess the affected controls. A migration to Microsoft 365, the addition of new stations or a modification of the network may make certain audit assumptions obsolete. THE proactive monitoring, that is to say the continuous observation of systems to spot anomalies before they disrupt the service, helps to monitor the environment after corrections. It completes the checks, without replacing them.
A geosynchronous backup, based on real-time replication to two geographically separated sites, can contribute to data resilience. However, it does not correct excessive access rights or vulnerable configuration. Flux Group offers geosynchronous backup solutions as well as IT support and cybersecurity services. To extend your approach, consult the cybersecurity guide for businesses in Switzerland.
IT security in Geneva: get support for the rest of the audit
An audit report can combine technical parameters, business risks and organizational decisions. An IT partner helps translate these findings into understandable measurements, identify dependencies between systems and coordinate the people involved. For an SME, the objective is not to add unnecessary procedures, but to address discrepancies according to their possible effect on activities, data and continuity of operations.
Support adapted to SMEs in Geneva and Switzerland
In Geneva, Meyrin, Vernier, Eaux-Vives, Collogny, Grand-Lancy and Petit-Lancy, the IT environments of SMEs vary depending on the tools, teams and activities. Flux Group supports companies with their IT and cybersecurity challenges, by linking audit findings to IT support, data protection and proactive infrastructure management. This approach makes it possible to clarify roles, coordinate corrections and maintain an overview of the systems concerned.
The main security errors observed during IT audits are not all corrected in the same way. Poorly defined access calls for a review of authorizations; an unclear procedure may require a governance decision and communication to teams. Support consists of distinguishing these needs, organizing their treatment and re-evaluating the measures when the environment changes. The audit thus becomes the starting point for ongoing monitoring, rather than a report to be archived.
Data localization is also one of the elements to consider. Hosting in Switzerland can contribute to data sovereignty, but does not alone guarantee compliance. Your analysis must take into account the data processed, access and the applicable legal context, in particular FADP. Flux Group’s IT support and cybersecurity services can be part of this approach.
Prepare for the next step after the report
Before an exchange with a specialist, gather the elements that facilitate the framing of actions. You don’t need to master every technical term in the report. Instead, prepare the information useful for the decision:
- the findings that concern you and the systems concerned;
- business activities that depend on these systems;
- measures already carried out or in progress;
- operational constraints, those responsible and decisions still awaited.
From these elements, an exchange can help clarify priorities, dependencies and next checks. You will be able to move forward with actions adapted to your context, without confusing a technical correction with a decision that is the responsibility of management or business teams.
Make safety a lasting reflex
The next step is not to look for a completely risk-free environment. It’s about establishing a way of deciding and acting that evolves with your business. The main security errors observed during IT audits can serve as benchmarks to review your practices when changing teams, tools or activities, rather than waiting for the next report.
Choose a monitoring point that you can maintain: a status of actions in progress, a periodic review of access or documented verification of a measure applied. This regularity helps management, teams and IT partners maintain a common understanding of priorities. It also allows you to approach data protection and business continuity as concrete management topics, adapted to the reality of your SME.
Move forward step by step, keeping the focus on essential activities and clearly established responsibilities. A structured approach makes security more understandable and easier to maintain over time.
Frequently asked questions about IT audits
Does an IT audit guarantee the security of an SME?
No. An IT audit identifies discrepancies within a defined scope, but does not guarantee the absence of incidents. It is necessary to distinguish between diagnosis, corrections and their follow-up. The main security errors observed during IT audits guide decisions, but do not certify definitive protection. Systems, uses and access evolve; the value of the audit therefore also depends on the implementation and verification of the recommendations.
Can an IT security audit disrupt the work of teams?
It is possible, depending on the scope, methods and timetable chosen. A desk review or interviews do not interact with systems in the same way that some technical tests do. Before starting, specify the objectives, the environments concerned and the intervention periods with business and IT managers. This preparation allows sensitive activities to be taken into account, without guaranteeing that no interruption will occur.
What documents should you prepare before an IT security audit?
Gather the elements available on your IT equipment, accounts and access, backups, internal procedures and distribution of responsibilities. An inventory of applications used by teams, even incomplete, can also help identify forgotten dependencies. This preparation facilitates exchanges, but is not an absolute condition to start. Do not place passwords or access secrets in ordinary documents.
Should we also audit the access of suppliers and service providers?
Yes, if external access exists and concerns the systems included in the audit. Document for each access its purpose, the accessible resources, the rights granted and the way in which it is managed at the end of an intervention. For example, access used for the maintenance of a business tool is not the same as an internal account. The analysis must remain proportionate to the systems concerned, without assuming that all suppliers present the same risk.
How often should you redo an IT security audit?
There is no universal frequency applicable to all SMEs. Reexamine the schedule after a significant change, such as a service migration, reorganization, or the addition of an activity that changes IT needs. Certain findings may justify a targeted control, while a complete audit covers a broader scope. Distinguishing these two approaches helps to adapt the effort to the observed change, without transforming a particular rhythm into a general obligation.
Does an IT audit automatically verify FADP compliance?
No. A security audit and a compliance analysis do not necessarily cover the same issues. The scope and skills mobilized determine the aspects examined. For a Geneva SME, the FADP constitutes the federal reference for personal data; LIPAD may also be relevant depending on the status of the organization and its activities. An IT audit is therefore not enough to automatically conclude that the company complies with all applicable rules.
