What does an IT security audit of the whole environment verify?
The audit gives leadership and IT a shared view of security before isolated fixes are launched. We focus first on situations that could cause a compromised account, a data leak, a service outage, lateral movement, or a loss of recovery capability.
The review connects the components together: an administrator account, VPN, business application, or backup can look correctly configured in isolation and still create a risk when combined with the rest of the environment.
The debrief should first distinguish risks requiring immediate correction from those that can be planned. It should also show which systems or access paths carry the most exposure and which actions reduce risk fastest.
Finally, the audit should make clear which workstreams require budget, an architecture tradeoff, or a governance decision.
What do we review across the IT environment?
Identity, accounts, and access
We review administrator accounts, MFA, SSO, dormant accounts, excessive permissions, and supplier access. The review also covers service accounts, keys, secrets, joiner and leaver processes, and separation between user and administrator identities.
We verify who can access what, with which level of privilege and from which environment. The goal is to prevent a compromised account or former supplier access from enabling unnecessary movement through the environment.
Network and external exposure
We review Internet-facing services, VPNs, remote access, firewalls, and segmentation. We compare them with user, server, and administration networks, site-to-site access, DNS, and certificates when relevant to the scope.
We map the main entry points and the paths that allow movement from one zone to another. Any necessary exposure should be known, limited, and monitored.
Servers, endpoints, and systems
We review operating systems, outdated versions, patches, hardening, and unnecessary services. The review can also cover local rights, privileged endpoints, antivirus or EDR, directory services, and Active Directory when relevant.
The review looks for configurations that would make compromise easier or allow a local attack to become an incident affecting the wider company.
Cloud, hosting, and environments
We review Cloud accounts and roles, production/test separation, storage, secrets, network rules, administration consoles, logs, public configurations, and critical managed services across AWS, Azure, GCP, or another provider.
We pay particular attention to administrator permissions, exposed resources, and the gap between what the team believes it configured and what is actually reachable. Cloud remains one part of the wider IT audit, not a standalone AWS or Azure review.
Critical applications and data
We connect critical applications and their data: ERP, CRM, business applications, SaaS, APIs, databases, technical accounts, data exchanges, dependencies, administration interfaces, and external integrations.
The goal is not to repeat a full code audit for every application. We mainly review how critical applications connect to the environment, which access they open, and which data they expose. A dedicated web application audit can complement this review when one component needs deeper analysis.
Backups, monitoring, and continuity
We review backups and restoration, their separation, retention, and access. We also review logs, alerts, monitoring, incident procedures, recovery capability, and critical dependencies.
A backup is useful only if it can actually be restored. We therefore review recovery capability as well as the existence of backup mechanisms.
IT audit, vulnerability scan, or penetration test: what is the difference?
A scan automatically detects some known vulnerabilities. A penetration test attempts to exploit a defined scope to assess how far an attacker could go.
An IT security audit is more transverse: it connects architecture, configurations, access, exposure, backups, systems, and technical organization to identify the most important risk scenarios. A penetration test can be recommended for a specific scope when the audit shows that an exposure deserves deeper testing.
How does the audit run?
01 — Scope definition
A 45-to-60-minute discussion with leadership, the CIO, or the IT lead defines the sites, environments, critical applications, suppliers, sensitive data, business constraints, and any recent incidents. The scope must be broad enough to understand critical dependencies, yet precise enough to produce useful conclusions.
02 — Access and documentation collection
Depending on scope, we gather the inventory, architecture, read-only accounts, configurations, network documentation, cloud consoles, backup policies, logs, monitoring tools, and supplier information. Read-only access is preferred whenever it provides the required evidence.
03 — Targeted interviews
The discussions usually involve the CIO or IT lead, infrastructure or cloud owners, critical application owners, and, where needed, the managed service provider. For a standard scope, 2 to 4 targeted technical discussions are usually enough; leadership mainly joins the scoping and debrief stages.
04 — Analysis and verification
We compare documented controls with what is actually configured. A finding is not ranked only because a tool generated an alert: we assess its exposure, the permissions needed to exploit it, and its possible consequences for the environment.
Risks are ranked according to impact, likelihood, exposure, remediation difficulty, and business dependencies.
05 — Debrief and remediation plan
A 60-to-90-minute debrief with leadership and the technical team presents critical risks, useful evidence, quick wins, structural workstreams, and the recommended correction order.
How long does an IT security audit take?
A transverse audit of a typical mid-sized or upper mid-market environment usually takes around 10 to 15 business days of work, spread across two to four calendar weeks depending on team and access availability.
Timing increases with multiple sites, several cloud environments, a large Active Directory, many critical applications, several suppliers, an offensive testing scope, or incomplete documentation. The scope is defined before starting so the audit does not expand without creating more value.
What do you receive at the end of the audit?
Leadership summary
A concise document covering the main risk scenarios, their business impact, the decisions to make, and the immediate priorities.
Risk map
For each significant finding: affected component, risk, possible consequence, priority, useful evidence, and recommendation.
Remediation plan
Immediate: address critical risks and quick wins. Within 30 days: complete priority corrections. Within 60 days: revisit the relevant access, configurations, or architecture. Within 90 days and beyond: launch structural workstreams.
Backlog the teams can use
Recommendations are turned into actions with an owner, priority, dependency, and indicative effort level.
Technical debrief
Leadership understands the decisions to make and technical teams understand what they need to fix. The report is not limited to vulnerability scanner screenshots.
What happens after the audit?
The audit can remain independent from remediation. If Koragence continues the engagement, we work through the backlog by priority: access, hardening, network, cloud, secrets, backups, monitoring, or application fixes depending on the findings.
Corrections can be grouped into short workstreams or integrated into a broader roadmap when several parts of the environment must evolve together. Access and cloud hardening or infrastructure security and operations can then become the natural next steps after the audit.
When should you launch an IT security audit?
The engagement is aimed at structured SMEs and mid-sized companies that already have an IT team, several tools, critical data or applications, cloud environments, suppliers, or multiple sites.
The audit is particularly relevant before a major transformation, opening the environment to new partners, or a change of CIO, provider, or technical team. It is also useful after years of accumulated tools, when no clear access map exists, when cloud and on-premise environments coexist, or when an incident, alert, customer request, or security investment requires concrete assurance.
