Managed cybersecurity: prevention, detection, response
Protecting the core of a business is not about buying a firewall. It is a continuous watch over perimeter, data, identities and people, run by people who do it for a living.
Security is not a product you install. It is a watch you keep.
As a managed security service provider we work alongside companies to protect their information systems continuously: prevention, monitoring, detection, incident response and steady improvement of the security posture.
Perimeter protection
Next-generation firewalling, VPNs and controlled remote access, SD-WAN, and security policies managed and kept current.
Detection and response
SIEM for event collection and correlation, threat monitoring, log analysis, and incident response with fast recovery plans.
Data protection
Endpoint protection with EDR and XDR, system hardening, identity and access management, immutable backup and ransomware defence.
One team watches the security events, the other watches the infrastructure.
SOC · Security Operations Centre
The watch dedicated to monitoring security events, analysing threats and handling cyber incidents. It detects, analyses and coordinates the response.
NOC · Network Operations Centre
The watch dedicated to infrastructure, connectivity, servers and performance. It keeps services running and catches anomalies early.
Together the two give a complete picture: security and operational continuity are not separate worlds, and whoever runs them together answers better to both.
Certifications and compliance support: security you can demonstrate.
Aesir operates to ISO 9001 and ISO/IEC 27001, 27017 and 27018. For companies within the scope of the NIS2 directive, that translates into practical support on governance, risk management, continuity and the protection of digital infrastructure.
ISO/IEC 27017 and ISO/IEC 27018 are attestations of conformity to the guidelines, valid in combination with ISO/IEC 27001:2022 certificate no. C2026-02420. NIS2 does not provide for certification: the correct wording is compliance support. Certificate details, dates and certifying body
The answers we are asked for most often.
Where do we start if we have never done anything structured?
With an assessment that captures the real picture: perimeter, access, backups, exposures. From there, a plan by priority, starting with the measures that cut the most risk for the least effort.
What does GDPR require in technical terms?
Data protection, access control, backups and traceability: GDPR compliance runs through concrete technical measures, not documents alone. Read the full article
What does an MSSP like Aesir do?
A managed security service provider looks after a company’s information security continuously: it designs the protective architecture, monitors events, detects threats, responds to incidents and improves the overall security posture over time.
We are a small company — are we really a target?
Yes, and often precisely because you are less protected. Most ransomware attacks hit small and medium businesses, where a systems outage or data loss lands immediately on production, revenue and reputation. Size is not a defence.
How does Aesir help with the NIS2 directive?
Aesir supports companies in scope for NIS2 on security governance, risk analysis and management, monitoring, incident response, operational continuity and documentation. The path starts with an assessment of where you are today.
Tell us how you work today.
Tell us what you protect today, and how you would find out if something went wrong. The first answer is an assessment, not a quote.
We reply within one working day. If you are already a client and need technical support, please use the ticket portal.
Do you know how your company would react to an attack today?
A security assessment tells you where you are exposed and what to fix first. No scaremongering, no obligation.
