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.

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.
What We Deliver
SIEM Management & Monitoring
Deployment and 24/7 operation of Microsoft Sentinel, Splunk, or Elastic Security. Custom detection rules mapped to MITRE ATT&CK, log source onboarding, alert tuning to minimize false positives, and continuous rule development as your environment evolves.
Endpoint Detection & Response
Managed EDR using CrowdStrike Falcon, SentinelOne, or Microsoft Defender for Endpoint. Agent deployment, policy tuning, 24/7 alert monitoring, and automated containment for endpoint-based threats including ransomware, fileless malware, and lateral movement.
Vulnerability Management
Continuous vulnerability scanning with Qualys, Nessus, or AWS Inspector. Risk-based prioritization considering CVSS, exploit availability, and asset criticality. Monthly vulnerability reports with remediation tracking and SLA enforcement.
Incident Response
Documented incident response procedures aligned with NIST SP 800-61. Containment within SLA (isolate endpoints, block IPs, disable accounts), forensic investigation, root cause analysis, and regulatory-grade incident documentation.
Compliance Monitoring

Managed Security Services — Enterprise Cybersecurity Partner FAQ
What is a managed security services provider (MSSP)?
An MSSP is an outsourced cybersecurity provider that monitors and manages your security infrastructure 24/7. Services typically include SIEM monitoring, endpoint protection, vulnerability management, and incident response. Unlike hiring individual security analysts, an MSSP provides a complete security operations capability with tools, processes, and skilled personnel for a predictable monthly fee. Opsio's MSSP services go beyond basic monitoring to include active threat investigation, containment, and remediation.
How is an MSSP different from MDR?
An MSSP provides broad security monitoring and management across your security infrastructure — SIEM, firewalls, endpoints, and compliance. MDR (Managed Detection and Response) is a more focused service specializing in advanced threat detection and active response, typically centered on EDR platforms. Opsio offers both MSSP and MDR capabilities. For organisations needing comprehensive security operations including compliance monitoring and vulnerability management, MSSP is the right fit. For those focused specifically on advanced threat detection and rapid response, MDR may suffice.
What SIEM platforms do you support?
We deploy and manage Microsoft Sentinel (Azure-native, excellent for Microsoft-heavy environments), Splunk Enterprise and Splunk Cloud (powerful for large-scale log analytics), Elastic Security (open-source-friendly, cost-effective for high-volume log ingestion), and QRadar for existing IBM customers. We recommend the platform based on your existing technology stack, log volume, and budget constraints.
How much does an MSSP cost?
Opsio's MSSP services range from $8,000-$25,000 per month depending on scope — number of log sources, endpoints, and service tier. This includes 24/7 SIEM monitoring, EDR management, incident response, and monthly reporting. Initial setup (SIEM deployment, log source onboarding, detection rule engineering) runs $15,000-$40,000. Compared to building an equivalent in-house SOC ($800K-$1.5M annually for staff, tools, and facilities), MSSP services represent 60-80% cost savings.
Do you provide incident response for breaches?
Yes. Incident response is included in our MSSP services — not an add-on with per-incident fees. When a threat is confirmed, we contain it immediately (endpoint isolation, IP blocking, account disabling), investigate root cause with forensic analysis, document findings for regulatory notification, and remediate the vulnerability that was exploited. For large-scale breaches requiring on-site response, we have a retainer-based IR offering with guaranteed 4-hour mobilization.
