What is ACDC?

Absolute security does not exist. That is why ACDC takes a holistic approach: detect attacks early, respond to incidents effectively and so minimise risk. Proactive, continuous and consistent.

ACDC – Active Cyber Defense Center is a managed SOC for companies in Austria, Germany and Switzerland. Built by snapSEC in 2022 together with A-Team Rocks, it is operated by Active Cyber Defense Center Service GmbH in Vorchdorf, Austria, a sister company of snapSEC GmbH. A team of analysts monitors your IT environment around the clock, rates alerts by criticality, escalates through agreed paths and supports containment and recovery.

Scope of service

Detect, respond, improve

ACDC is more than monitoring: analysts assess alerts, respond to incidents together with you and keep fine-tuning detection. That takes the load off your IT team, including at night and at weekends.

Detect

24/7 security monitoring & threat detection

The ACDC security operations centre (SOC) monitors your IT environment continuously and analyses incoming log data and events in real time.

  • Continuous monitoring of your IT environment, including nights, weekends and public holidays
  • Real-time analysis of log data and events for security-relevant anomalies
  • Automated and manual detection based on current attack techniques
  • Incidents prioritised by criticality, context and the systems affected

OptionalConnect your existing SIEM, EDR or XDR systems, or use the ACDC platform

Respond

Incident handling & threat response

When it matters, clarity counts: what happened, how critical is it and what needs to happen now?

  • Thorough initial assessment and triage of detected security incidents
  • Close coordination on critical incidents through agreed escalation paths
  • Support with forensic analysis and technical containment of the attack
  • Recommendations on containment, hardening and recovery of affected systems

OptionalIntegration into your existing incident response processes and playbooks

Improve

Strategic support & continuous improvement

Good detection is not a one-off: it comes from continuous fine-tuning with your environment and goals in mind.

  • Ongoing optimisation of detection rules and use cases
  • Regular meetings with security consultants, e.g. monthly or quarterly
  • Support in choosing relevant log sources and monitoring goals
  • Support with compliance requirements, e.g. ISO 27001 and NIS2

OptionalCan be extended with threat hunting, purple teaming and retainer models

Use case

No in-house 24/7 team

Your IT team works during the day; attacks ignore office hours. ACDC takes over monitoring and first response around the clock.

Use cases

When a managed SOC pays off

Typical reasons for ACDC: regulatory duties, insurer requirements and an IT team that cannot be there around the clock.

NIS2

Detect, handle and report incidents on time

NIS2 requires incident handling measures (Art. 21) and tight reporting deadlines (Art. 23). ACDC delivers the technical part: detection around the clock, agreed escalation and reports as the basis for your notification. Your organisation remains responsible for reporting.

NIS2 reporting deadlines, Art. 23

ACDC: detect, assess, escalate, report

Your organisation: notify the CSIRT or authority

  1. 0 hBecoming aware of a significant incident
  2. 24 hEarly warning
  3. 72 hNotification with initial assessment
  4. +1 monthFinal report after the notification

Insurance

Cyber insurance requirements

If your insurer asks for ongoing monitoring and a defined response, reports and escalation paths show how you deliver it.

What ACDC provides

  • Monitoring around the clock
  • Agreed escalation paths
  • Reports and regular review meetings

Which requirements apply, and whether they are met, is determined by your insurance policy.

How they differ

ACDC or managed SIEM?

Both work with log data. The difference: who detects attacks, who responds and whether someone is watching around the clock.

Process

From first call to 24/7 operations

No standard package: you get a monitoring and response model that fits your IT landscape.

  1. Initial call

    You describe your IT landscape, existing security tools and goals. Together we clarify whether ACDC fits or another service does.

  2. Define the monitoring model

    Define relevant log sources and monitoring goals, connect existing SIEM, EDR or XDR systems or use the ACDC platform.

  3. Agree the response

    Agree escalation paths and contacts, integrated into your incident response processes and playbooks if you wish.

  4. 24/7 operations with regular reviews

    Monitoring around the clock, reports and regular review meetings with a named contact. Detection rules are continuously fine-tuned.

FAQ

Frequently asked questions about ACDC

What is a managed SOC and what does ACDC do?

A managed SOC is an external security operations centre that monitors your IT environment as a service and responds to attacks. To do this, ACDC analyses log data and events around the clock, detects anomalies automatically and manually, prioritises incidents by criticality and escalates critical incidents through paths agreed with you. ACDC also supports forensic analysis, containment and recovery and continuously optimises its detection rules. You do not need your own shift team for any of this.

Do we have to replace our existing security tools?

No. Existing SIEM, EDR or XDR systems can be connected to ACDC; alternatively, you use the ACDC platform, which brings security-relevant data together in one place. You and ACDC decide together which log sources make sense and which monitoring goals apply. The result is a monitoring and response model that fits your IT landscape, rather than a standard package that would force you to rebuild your environment.

What happens if ACDC detects a critical incident at night?

An analyst assesses the incident and reports it to your designated contacts along the agreed escalation path, including outside office hours. ACDC then works with you to contain the attack technically, supports the forensic analysis and recommends measures for containment, hardening and recovery of the affected systems. If you have your own incident response processes or playbooks, ACDC is integrated into them so that everyone knows who decides what when it matters.

Does ACDC help with implementing NIS2?

Yes, ACDC supports the technical requirements for detecting and handling security incidents that NIS2 sets out in Art. 21. For the reporting obligations under Art. 23 (early warning within 24 hours, notification within 72 hours, final report no later than one month after the notification), detection around the clock, agreed escalation paths and reports provide the basis. That alone does not make you compliant: your organisation has to report, and organisational measures remain your responsibility. This overview is not legal advice.

Does ACDC help with cyber insurance requirements?

Yes, if your insurer requires ongoing monitoring, detection and a defined response to incidents. ACDC provides building blocks for this, such as round-the-clock monitoring, agreed escalation paths, reports and regular review meetings. With these you can show how your organisation detects and handles attacks. Which requirements apply and whether they are met is determined by your insurance policy. We therefore recommend comparing your insurer's questionnaire with the agreed monitoring scope.

What is the difference between ACDC and managed SIEM?

With ACDC, analysts take over detection and response around the clock; with managed SIEM, snapSEC only runs the platform and your own team detects and responds. Managed SIEM & security data lake is a SIEM platform based on Elastic, operated by snapSEC, with retention from days to several years; you manage rules and alerts yourself. ACDC is the right fit if you lack your own 24/7 team. An existing SIEM can be connected to ACDC.

How do we stay informed about our security posture?

Through regular review meetings, clear reports and a named contact who knows your environment. In these meetings with security consultants, for example monthly or quarterly, you discuss incidents, the threat landscape and improvements to log sources, detection rules and use cases. You get more than data: concrete recommendations for action. If needed, ACDC can be extended with threat hunting, purple teaming or retainer models.

Which companies is ACDC suitable for?

ACDC suits companies in Austria, Germany and Switzerland that want protection around the clock but cannot or do not want to build their own 24/7 security team. Typical triggers are NIS2 obligations, cyber insurance requirements or an IT team that is not available at night and at weekends. According to acdc.onl, ACDC currently protects over 25,000 digital assets at more than 30 companies.
