IT systems security — tools and services that genuinely protect your organization
Systems security is not a single box or one product on the shelf. It is a tailored blend of solutions sized to your organization — endpoint protection, privileged access control, backup, monitoring, employee awareness. Each building block answers a concrete requirement: NIS2 (Article 21 — technical and organizational measures), ISO/IEC 27001:2023 (Annex A — access control, cryptography, event logging), DORA (ICT risk management in financial services), as well as Polish KSC and UKSC regulations after the 2024 amendment.
Virtline is TÜV NORD-certified to ISO/IEC 27001:2023 and selects the elements that genuinely fit your risk profile and budget. We don’t sell catalogs — we implement. This page is a map of our competencies in systems security technology: 12 solutions in 4 groups. Pick the area you care about or start with a free consultation.
What IT systems security covers at Virtline
Six technological pillars combined into one coherent protection model — sized to your company and compliance requirements.
Endpoint & Workplace protection — EDR, MDR, business-class antivirus, laptop and mobile fleet management (UEM/MDM).
Identity & Access — multi-factor authentication (MFA), privileged access management (PAM), access control aligned with ISO 27001 A.5.15.
Data and file transfer — 3-2-1 backup rule, managed file transfer (MFT), corporate email protection against phishing and ransomware.
Vulnerability management — cyclical infrastructure scanning, CVE classification by CVSS, remediation plan tied to audits.
Awareness & training (SAT) — phishing simulations, employee courses, progress reporting — required by NIS2 Article 21 and ISO 27001 A.6.3.
Inventory & monitoring — Statlook for hardware and license inventory, continuous event monitoring, integration with audit processes.
Group 1 — Endpoint & Workplace protection
Every endpoint device — laptop, desktop, smartphone — is a potential entry point into your company. This group of solutions protects them from malicious code, monitors behavior, and lets administrators react faster than eight hours after an incident.
EDR — Endpoint Detection and Response — detects threats that bypass antivirus and lets you reconstruct attack timeline step by step.
MDR — Managed Detection & Response — EDR plus a SOC analyst team in 24/7 mode. For companies without an internal cyber unit.
UEM / MDM — laptop and mobile fleet management from a single console. Policy enforcement, remote wipe, compliance reporting.
Group 2 — Identity & Access
Most incidents start with a leaked password or a hijacked privileged account. In this group we eliminate the single largest risk — uncontrolled access to critical systems.
MFA — multi-factor authentication — second factor on every critical account. Baseline of every NIS2 and ISO 27001 audit.
PAM — Privileged Access Management — control, recording and password rotation for admin accounts. Required by DORA Art. 9 and ISO 27001 A.8.2.
Group 3 — Data, email and file transfer
Data is your company’s value. This group ensures it doesn’t disappear (backup), doesn’t leak via email (Email Security), and doesn’t escape through partner transfers (MFT). Required pillar of every NIS2 and DORA audit.
MFT — Managed File Transfer — encrypted, auditable file transfer between systems and partners. Required by PCI DSS, HIPAA, ISO 27001 A.5.14.
Email Security — anti-phishing, anti-spam, sandbox for attachments, GDPR-compliant archiving. Main attack vector in Europe 2024-2025.
Group 4 — Vulnerability, awareness, inventory
Technology alone isn’t enough. This group combines technical scanners with the weakest link of every organization — the human. Together they deliver the visibility and control demanded by every NIS2 and ISO 27001 auditor.
Vulnerability Management — cyclical scanning, CVE prioritization by CVSS, remediation path tied to audits.
SAT — Security Awareness Training — phishing simulations, micro-training, compliance reports. Required by NIS2 Art. 21 and ISO 27001 A.6.3.
Who we tailor systems security for
We particularly help organizations that:
- are essential or important entities under NIS2 (energy, transport, healthcare, finance, ICT, water, food, critical manufacturing)
- operate in financial services and must implement DORA
- hold or are pursuing ISO/IEC 27001:2023 certification
- process personal data and must demonstrate GDPR compliance
- implement KSC requirements after the 2024 amendment or prepare for an ISA 315 audit
- want to minimize ransomware and data-leak risk without overspending on enterprise tooling
Size of companies we work with: 50 to 1,500 workstations. We operate remotely across Poland and on-site in Warsaw and Lublin, with international clients served remotely.
Frequently asked questions about IT systems security
Where do we start building systems security in our company?
Start with inventory and risk assessment, not with tool procurement. Without knowing what systems you have, what data you process, and which regulations apply, you’ll buy solutions that don’t fit your needs. We always propose an NIS2 audit or ISO 27001-aligned audit as the starting point. Only the audit report tells you what to buy first — usually MFA everywhere, immutable backup, EDR on all endpoints, SAT for employees.
Does our company need to comply with NIS2?
If you employ over 50 people or have annual revenue over EUR 10 million and operate in a sector listed in Annex I or II of the directive (energy, transport, healthcare, water, digital infrastructure, ICT, public sector, finance, critical manufacturing, food, research) — then yes. After the 2024 KSC amendment, obligations are enforced in Poland by CSIRT NASK, with penalties up to EUR 10 million or 2% of revenue. An NIS2 audit definitively answers whether you fall under the directive and which gaps to close.
How does EDR differ from antivirus, MDR from EDR, XDR from MDR?
Antivirus (EPP) blocks known threats by signature. EDR goes further — analyzes process behavior, detects attacks without signatures, records full event timelines, and lets you reconstruct breach paths. MDR is EDR plus an external SOC team monitoring alerts 24/7 instead of your admin. XDR extends visibility to email, network and cloud — but in practice most SMBs are well served by a properly deployed EDR (or MDR as a service). See pages EDR and MDR.
How much does systems security cost for a 100-person company?
Cost depends on scope. A baseline NIS2 compliance package for a 100-person company (EDR on endpoints + MFA + immutable backup + quarterly SAT + monitoring) starts around EUR 3,000-5,000 net per month in a subscription model. A full package with PAM, MDR as a service and vulnerability management runs EUR 7,000-15,000 per month. We prepare a quote after an initial conversation — typically 30 minutes is enough to scope the work.
Can I buy just one tool from you, like only EDR?
Yes. We don’t require signing an all-or-nothing package. You can buy a single solution (EDR, MFA, backup) together with deployment and support. We suggest a conversation about the whole picture though — often it turns out the gap you feel most isn’t the one you came in for. We recommend an IT security audit as a free starting point.
Do you serve companies outside of Poland?
Yes. The majority of our deployments run remotely — EDR/MDR console configuration, MFA policies, backup, SAT. On-site presence is needed occasionally (e.g. physical server room audit or workshop training). We work with clients across the EU, with documentation and communications in English. Contact us — we’ll explain how the collaboration model works.
