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. This page is specifically about Opsio's MSSP practice — security operations, threat detection, response, and compliance. For general IT operations under one umbrella, see our managed service provider service. 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. For deeper engagement on cloud-native security architecture — IAM, KMS, posture management, zero-trust networking — pair this MSSP service with our cloud security service practice and our IT cloud security assessment for baseline benchmarking.
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. Where customers want EDR/XDR specifically — endpoint-centric detection and response without the broader SIEM/compliance footprint — we offer a focused SeqOps XDR/EDR security service operated by the same SOC team.
Modern MSSPs sit at the intersection of detection, response, and compliance — three disciplines that used to belong to separate teams. Detection requires SIEM engineering: writing detection rules against MITRE ATT&CK, tuning false positives, and onboarding log sources from clouds, identity providers, endpoints, network devices, and SaaS applications. Response requires SOAR automation that can isolate endpoints, disable accounts, block IPs, and quarantine emails within seconds rather than waiting for human approval on every routine action. Compliance requires evidence collection, control validation, and audit-ready reporting against frameworks like ISO 27001, SOC 2, NIS2, GDPR, PCI-DSS, and HIPAA. Opsio's MSSP integrates all three so customers do not have to coordinate across multiple specialist vendors.
Threat hunting and proactive testing are part of the standard service, not add-ons. The team runs hypothesis-driven hunts each quarter against the current MITRE ATT&CK technique landscape — looking for indicators of compromise that bypassed automated detection, particularly living-off-the-land techniques and lateral movement patterns that signature-based detection misses. Quarterly red-team exercises and penetration tests (see our penetration testing essentials post) validate that the detection-and-response stack actually works under attack conditions, not just under tabletop scenarios.

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.
MSSP vs MDR vs XDR — what's the practical difference?
MSSP is the broad service category: continuous monitoring, SIEM management, vulnerability management, compliance reporting — covering the entire security stack. MDR (Managed Detection and Response) is a tighter scope focused on advanced threat detection and active response, typically centered on endpoint and identity signals, suitable for organisations that already have compliance and vulnerability management in-house. XDR (Extended Detection and Response) is a tooling pattern that unifies endpoint, identity, email, and cloud signals into a single platform with native correlation — vendors like CrowdStrike Falcon, Microsoft Defender XDR, and SentinelOne Singularity ship XDR products that MSSPs operate. Opsio offers both MSSP (full-spectrum) and MDR (focused) tiers, and operates XDR platforms natively as part of either tier.
What does each SOC analyst tier (T1/T2/T3) actually do?
T1 analysts triage every alert that reaches the SIEM, enrich with threat intel and environmental context, and either close (false positive / benign) or escalate. They are the volume tier — typical 100-300 alerts per shift. T2 analysts investigate escalations, perform deeper forensic work, drive containment actions (endpoint isolation, account disable, IP block), and write the incident timeline. T3 analysts handle complex multi-stage incidents, threat hunting, detection engineering, and post-incident RCAs; they also lead the response when something looks like a targeted attack rather than commodity malware. Opsio staffs all three tiers across follow-the-sun shifts so the right level of expertise is available every hour of the year.
Microsoft Sentinel vs Splunk vs CrowdStrike Falcon — when does each fit?
Microsoft Sentinel is the right choice when the customer is Microsoft-heavy (Entra ID, Defender, Exchange Online, Intune) and wants Azure-native consumption pricing and tight integration with Microsoft's threat-intel ecosystem. Splunk is the right choice for high-volume log analytics at scale, complex correlation requirements across many heterogeneous sources, and customers with existing Splunk skills in-house. CrowdStrike Falcon is the right choice when endpoint and identity protection is the priority — Falcon is XDR-first, with very strong native EDR, and pairs well with a separate SIEM for compliance-driven log retention. Opsio operates all three and selects based on the customer's existing estate, log volume, and budget shape.
24/7 vs business-hours coverage — is 24/7 always worth it?
For any organisation with revenue-critical online services, customer data exposure risk, or regulatory incident-reporting obligations, 24/7 is effectively non-negotiable: attackers prefer to operate outside business hours precisely because defender coverage drops. For low-criticality internal-only workloads with no regulatory exposure, business-hours plus on-call may be sufficient — but the cost differential is usually smaller than expected (often 30-40%, not 100%), because the SOC platform, detection engineering, and response automation are the same; what differs is shift staffing density. Most Opsio MSSP customers settle on full 24/7 once they cost out the incident-cost asymmetry.
What are the incident response SLAs?
Standard MSSP incident response SLAs: P1 (active compromise, data exfiltration in progress, ransomware detonation) acknowledged within 5 minutes and contained within 30 minutes. P2 (confirmed threat, no active exfiltration) acknowledged within 15 minutes, contained within 2 hours. P3 (policy violation, suspicious-but-unconfirmed) acknowledged within 30 minutes, investigated to determination within 4 hours. All response SLAs carry financial service credits if missed. For retained IR engagements requiring on-site forensic response, mobilisation is 4 hours from declaration.
What compliance frameworks do you support with audit-ready reporting?
ISO 27001 (Annex A controls evidence, internal audit support), SOC 2 Type II (Trust Services Criteria mapping, continuous control monitoring, auditor liaison), NIS2 (incident reporting workflows for essential and important entities, supply chain risk evidence), GDPR (breach notification within 72-hour window, lawful basis documentation, DPIA support), PCI-DSS (quarterly scans, file integrity monitoring, segmentation testing), HIPAA (access logs, encryption attestation, audit trails). Reports are exported in formats acceptable to major auditors — KPMG, EY, PwC, Deloitte — and Opsio can liaise directly with the audit team during fieldwork.
