Managed Security Services — Enterprise Cybersecurity Partner
Cybersecurity threats evolve faster than most organisations can hire and train talent. Building an in-house security operations center requires six or more full-time analysts, SIEM licensing, EDR tools, and continuous training — easily exceeding $1 million annually. Opsio operates as your managed security services provider (MSSP), delivering 24/7 SIEM monitoring, threat detection, incident response, vulnerability management, and compliance reporting at a fraction of the cost of building equivalent capability internally.

What is Managed Security Services?
A managed security services provider (MSSP) is a third-party organisation that delivers outsourced monitoring, management, and operational support for an enterprise's security infrastructure on a continuous basis. Core MSSP responsibilities typically include 24/7 SIEM monitoring and log correlation, threat detection and alerting, incident response and containment, vulnerability management and patch prioritisation, endpoint detection and response (EDR) management, and compliance reporting against frameworks such as ISO 27001, SOC 2, NIST CSF, and the EU NIS2 Directive. Practitioners commonly operate toolsets spanning SIEM platforms such as Microsoft Sentinel and Splunk, cloud-native detection services such as AWS GuardDuty and AWS Security Hub, EDR solutions, and infrastructure-as-code pipelines built on Terraform to enforce security baselines programmatically. Pricing varies considerably by scope: analyst estimates frequently cite entry-level MSSP engagements beginning around $5,000–$15,000 per month, while full-spectrum enterprise programmes covering SOC staffing, SIEM licensing, and compliance management can exceed $50,000 per month, compared to internal SOC build-out costs that routinely surpass $1 million annually when headcount, tooling, and training are factored in. The vendor cohort most cited in this space includes IBM Security, Fortinet, Optiv, AT&T Cybersecurity, and Secureworks. Opsio serves mid-market and Nordic enterprise clients as an MSSP operating a 24/7 NOC with a 99.9% uptime SLA, delivered across its Sweden headquarters in Karlstad and an ISO 27001-certified delivery centre in Bangalore, backed by AWS Advanced Tier Services Partner and Microsoft Partner accreditations covering cloud-native detection, response, and compliance automation.
Your Trusted Managed Security Services Provider
The cybersecurity skills shortage means there are 3.5 million unfilled security jobs globally. Even organisations that can hire security analysts struggle to retain them, maintain 24/7 coverage, and keep skills current as threats evolve. Meanwhile, attackers operate around the clock with industrialised toolkits. The mismatch between attacker capability and defender capacity is the core problem that managed security services address. Opsio's managed security services cover the complete security operations spectrum: SIEM deployment and management (Microsoft Sentinel, Splunk, Elastic Security), endpoint detection and response (CrowdStrike, SentinelOne), vulnerability management (Qualys, Nessus), email security, identity threat detection, and incident response. Our analysts monitor your environment 24/7, investigate alerts, contain threats, and provide forensic analysis for confirmed incidents. We operate under your security policies and regulatory requirements — acting as your security team, not as an external black box.
The difference between Opsio and commodity MSSPs is depth of service. Many MSSPs forward alerts to your team with a severity tag. Opsio investigates every alert to a determination — true positive, false positive, or benign activity. For true positives, we contain the threat, investigate root cause, and remediate. You receive actionable intelligence, not alert noise. Monthly threat briefings and quarterly security posture reviews ensure continuous improvement.
