24/7 Security Operations Centre: someone watching your environment even while you sleep

A SOC (Security Operations Centre) is the team of analysts and the technology that monitor your systems around the clock, detect threats and respond to incidents. In the ‘as a service’ model you rent a ready-made team and platform instead of building your own three-shift SOC. For a company in scope for DORA or NIS2, it’s how you get continuous monitoring and proof of due diligence without staffing a round-the-clock rota.

Executive summary: Most attacks land at night and at the weekend — exactly when your own IT team isn’t watching. Building a 24/7 SOC from scratch means three shifts of salaries, tool licences and constant churn; out of reach for most companies. As a service, you get the same coverage for a fixed monthly fee. For one client in scope for NIS2 we detected and blocked an advanced phishing attack within 15 minutes and cut irrelevant alerts reaching their team by 99% (source: Tenesys client case). You start with a monitoring gap review: we show you your blind spots.

Hackers Don’t Operate During Business Hours

Your protection must be ready for that. Our Security Operations Center (SOC) is a team of analysts who monitor your infrastructure 24/7, detect threats, and respond immediately to every incident, ensuring peace of mind and security for your business.

Four Reasons Why Companies Are Attacked Without Warning

Most companies discover they’ve been attacked only after the attacker has been inside for weeks. Not because security failed. Because no one was watching.

The after-hours threat.

Attacks most often come at night and at weekends, when nobody is watching the screens. Impact: you learn about a breach when the damage is already serious, not when it starts.

Drowning in alerts.

Systems generate thousands of notifications; the team can’t tell a real attack from a false alarm. Impact: the genuine signal is lost in the noise — and that’s the one you miss.

Missing specialist skills.

Responding to an advanced attack needs rare skills your internal IT team doesn’t have. Impact: in a real incident you improvise instead of following a procedure.

The astronomical cost of an in-house SOC.

Round-the-clock cover means several roles across three shifts plus licences. Impact: your own SOC is out of reach, and the risk goes unmanaged.

Case study

See How It Works in Practice

Client:

A company from the TSL sector, subject to CSCA/NIS2 requirements

Challenge:

The company needed to ensure 24/7 security monitoring to meet regulatory requirements and protect critical data, but could not afford to build its own SOC.

Solution:

We implemented our 24/7 SOC service. We integrated their cloud environment with our SIEM platform, deployed EDR on endpoints, and initiated 24/7 monitoring.

Results:

Detection and blocking of an advanced phishing attack within 15 minutes of its initiation.

Achievement of full compliance with monitoring and incident response requirements.

Reduction of irrelevant alerts reaching the client’s team by 99%.

Your company can also be under constant expert protection. Let’s discuss how SOC outsourcing can strengthen your security.

Our service

Comprehensive Protection in The SOCaaS Model

We operate as your specialized, external security department. We provide people, processes, and technology to protect your business.

Continuous monitoring and analysis 24/7/365

Our analysts analyze events in your network, servers, and cloud around the clock, looking for signs of unusual activity.

Incident detection and response (MDR)

We not only detect threats but actively respond to them as part of our Managed Detection and Response service, stopping attacks in real time.

Proactive threat hunting

Our experts proactively search your systems for hidden, advanced threats.

Advanced SIEM and XDR technology

We base our operations on SIEM platforms (Microsoft Sentinel, Wazuh) for event correlation and Sophos XDR for real-time threat detection and response—on endpoints, in the network, and in the cloud.

Reporting and compliance support

You receive regular security status reports and support in audit processes.

Technologies Behind Our Protection

Our process

Your Path to Complete Security

We begin every SOC implementation by understanding your environment. Onboarding takes approximately 4 weeks. After this time, your company is under full 24/7 protection.

1.

Analysis and scope definition

We start by understanding your business. Which systems are critical, what data requires protection, and what are your compliance requirements. We define the monitoring scope and agree on SLAs.

2.

Data source integration and technology deployment

We install agents, connect log sources, and integrate our SIEM platform with your environment: servers, endpoints, cloud, and applications.

3.

Calibration and runbook creation

We learn your environment. We fine-tune correlation rules, eliminate false alarms, and create detailed response procedures for every threat scenario.

4.

Full 24/7/365 protection

Your company is under constant supervision by our analysts. We detect threats, respond to incidents, and regularly report on security status.

Frequently Asked Questions

Antivirus and EDR protect a single device and block what they recognise. A SOC looks wider: it joins events from all your systems at once, correlates them and catches complex attacks that deliberately slip past individual defences. It also adds people — analysts who verify the signal and respond.

IT monitoring watches whether systems are up: availability, performance, load. A SOC watches whether they’re secure: it detects intrusions, suspicious logins and attacks. They’re two different jobs — one answers ‘is it running’, the other ‘has someone broken in’. They can run together, but they’re separate services.

About four weeks to full coverage. We begin with analysis and scope, then connect your data sources and integrate the SIEM, then calibrate the rules and write response runbooks. Only a calibrated SOC goes fully 24/7 — so it isn’t drowning in false alarms from day one.

You pay a fixed monthly subscription based on the number of monitored resources and the SLA level you choose. No per-incident charges and no surprises on the invoice. That’s one of the main advantages over an in-house SOC, where the cost is three shifts of salaries, tool licences and constant staff churn.

No. The SOC integrates with what you already have — firewalls, EDR/XDR, cloud logs — and strengthens it rather than replacing it. You usually don’t buy new tooling from scratch; we use your existing data sources and add missing pieces only where there are real gaps in visibility.

We ingest logs and security event metadata, not your business data or customer information — those stay in your environment, and transmission is encrypted. The scope and handling are agreed up front and written into the contract, which also matters for DORA and NIS2 audits.

Once a threat is confirmed, we run a runbook agreed in advance: we isolate the affected system, notify the people you’ve named and contain the attack together before it spreads. Everything is documented — you get a trail of events and decisions to use in your incident reporting to regulators.

Yes — it’s one of the main reasons financial-sector and critical-infrastructure companies adopt a SOC. Both regulations require continuous monitoring and incident reporting within set timeframes. A SOC delivers both: round-the-clock detection plus a documented response process you can put in front of an auditor.
