IT security
We help decide which weaknesses to address first, who owns the work and how to check the outcome. We combine scan findings with internet exposure, business impact and team capacity. Start with a review of key assets or ask us to operate a recurring programme.

A scan identifies known vulnerabilities and misconfigurations; it does not by itself prove an attack would succeed. CTEM (Continuous Threat Exposure Management) is a recurring cycle of scoping, finding exposures, prioritising, validating and organising remediation. Validation checks how controls perform in agreed scenarios. Remediation means applying a patch, changing configuration or reducing risk, and the outcome needs to be checked again. A report does not mean a weakness has been fixed, and business acceptance of risk is not a technical fix.
We agree which work belongs to the vulnerability programme and which needs a separate scope.
TÜV NORD Polska has certified Virtline’s information security management system to PN-EN ISO/IEC 27001:2023-08. The published certificate states its scope and validity.
View Virtline’s certificateBefore work starts, we agree access, service impact and acceptance criteria. We do not assume every weakness can be fixed immediately.
We define servers, workstations, networks, web applications, containers, public services, cloud and industrial systems (OT/ICS). We review privileged and service accounts, remote access, administration interfaces, unsupported systems, dependencies and owners. Methods reflect asset sensitivity.
We configure the scanner, asset groups, credentials, policies, exclusions, schedule and result retention. Within the agreed scope, we run internal and external scans with or without credentials. We review pilot findings with administrators and application owners.
We agree remediation order, deadlines and ticket workflows. We consider Splunk, Microsoft Sentinel, Energy LogServer or Wazuh for event analysis, and Jira, ServiceNow or GLPI for tasks. Connections, including patch management, depend on available versions, licences and interfaces.
We assign tasks to owners and carry out agreed changes. We check the outcome with a scan or repeated validation. We agree reviews of open tasks, exceptions and recurring issues. A one-off assessment, tool deployment and ongoing operation by Virtline are separately agreed scopes.
Practical scope
Results show findings alongside decisions, progress and limitations.
Scope, scan dates, authentication method and exclusions; CVE, affected service and owner. We compare findings with CVE/NVD and vendor advisories, investigate false positives and group duplicates.
Critical, high and medium priorities, agreed deadlines (SLAs) and tasks for administrators, application owners, suppliers and security staff. We record dependencies, downtime risks, change windows, rollback plans and escalation to business decision-makers.
A re-scan or validation, patch versions, configurations and ticket approvals. We distinguish a fixed weakness, reduced risk and an open issue. Temporary risk acceptance has a business owner, rationale, compensating controls, expiry date, review date and conditions for ending the exception.
Technical details, risk trends, overdue actions, recurring root causes, exposed systems and budget decisions. The material can support ISO 27001, NIS2, DORA and customer assessments; it does not confirm compliance.
WithSecure Elements Exposure Management is an example of a platform combining device, identity, cloud, network and external attack-surface data to assess exposures and attack paths. Picus Security Validation evaluates controls through attack-technique simulations, checking prevention, detection and event logging by firewalls, EDR, SIEM or email protection. These are different roles, not interchangeable CVE scanners. Technology evaluation and test conditions are agreed for the specific environment; naming these products does not imply a Virtline partnership or a purchase recommendation. We do not guarantee detection of every weakness, disruption-free changes or complete security after a successful test.
We select from Tenable Nessus, Tenable One Vulnerability Management (formerly Tenable.io), Tenable Security Center (formerly Tenable.sc), Qualys VMDR, Rapid7 InsightVM, OpenVAS/Greenbone and GFI LanGuard. We consider assets, cloud and on-premises environments, cost, retention and team capacity. Qualys VMDR combines inventory and prioritisation; patch deployment requires the relevant capability and subscription. InsightVM supports risk assessment and can work with InsightIDR. We check scanning, updating and integration scope before selecting a specific version.
The schedule depends on exposure, changes and the impact of scanning on services. Weekly incremental scans and monthly full authenticated scans can be a starting point for agreement. Additional checks follow critical CVEs, service launches, infrastructure changes, major updates and remediation. Recurring scanning does not mean a round-the-clock incident-response team.
CVE identifies a vulnerability, CVSS describes technical severity, EPSS estimates exploitation likelihood and the CISA KEV catalog lists vulnerabilities exploited in real attacks. We combine these signals with exploit and patch availability, internet exposure, service importance, data, downtime impact and existing safeguards. A high scanner score alone does not replace a business risk assessment.
We agree an owner, decision deadline and dependencies on vendors or change windows. Critical CVEs follow an agreed urgent workflow: check exposure, decide on a patch or workaround, notify owners and monitor for exploitation attempts. Options include firewall or WAF rules, segmentation, VPN, disabling a vulnerable function, EDR, MFA, configuration hardening or a detection rule. Suitability depends on the weakness; these measures do not always remove it. After the change, we check residual risk and whether escalation is needed.
Describe assets, existing scanners, open vulnerabilities, audit deadlines and change windows. Information on system owners, existing exceptions and expected handling of findings will help. Do not send passwords or confidential reports through the form.
