Managed SIEM Services: Turnkey Threat Detection & Compliance Without the Complexity
Buying SIEM software off the shelf is like buying a high-performance engine in parts: you have to build parsers, write correlation rules, tune out false positives for months, and reconfigure everything every time something changes. Computerease Managed SIEM is turnkey. You tell us what needs monitoring, and our team handles ingestion, parsing, rule creation, and tuning from day one.

Quick Answer
Computerease provides Managed SIEM (Security Information and Event Management) for businesses in Missouri and Illinois: centralized log collection from firewalls, servers, endpoints, and cloud services, analyzed in real time by our 24/7 SOC. SIEM is the data; the SOC is the human intelligence that turns it into action, identifying anomalies like an unusual login location or a server transferring large volumes of data at 3 a.m. Our team handles the technical work of connecting log sources, configuring rules, tuning alerts, and maintaining the platform, so your internal team doesn’t have to build and operate a SIEM on its own.
What SIEM Actually Does
SIEM aggregates log data from across your entire IT environment, firewalls, servers, endpoints, cloud services like Microsoft 365 and AWS, applications, into one centralized platform. On its own, that is just a pile of logs. Paired with a 24/7/365 SOC, it becomes the way threats actually get caught.
- Visibility: you cannot protect what you cannot see, SIEM provides one view across your entire environment.
- Threat Detection: sophisticated attacks like ransomware, lateral movement, and privilege escalation get identified before they cause damage.
- Forensics: if a breach happens, SIEM logs are the flight recorder that shows exactly what happened, how, and what was taken.
What’s Included
- Turnkey Implementation: zero configuration required from you, we handle ingestion, parsing, and rule creation.
- 24/7/365 SOC Monitoring: real-time analysis around the clock, since attacks do not happen only on business hours.
- Human Intelligence, Not Just Automation: automated tools catch known threats; our analysts catch the anomalies software misses.
- Cloud-Native Coverage: log ingestion from Microsoft 365, Azure, AWS, Google Workspace, and SaaS applications, no servers to buy.
- Custom Rule Building: a large library of correlation rules applied immediately, with custom rules built for anything specific to your environment.
Watching for AI-Related Anomalies, Too
An AI tool with broad access to email and files behaves differently than a normal user account, and that is exactly the kind of pattern SIEM correlation rules are built to catch: unusual data access volume, requests from unexpected locations, or activity outside normal hours.
As AI tools get adopted, we extend log monitoring to cover that activity the same way we cover any other account, so unusual AI-related access gets flagged instead of blending into the normal noise of a busy Microsoft 365 tenant.

Technology Services That Work Alongside Managed SIEM
Managed SIEM is the log intelligence layer. Computerease also provides the rest of your technology and security under the same flat-rate, family-owned model.
Scalable for Every Business Size
For Small and Medium Businesses
- Affordable, Tiered Pricing: cost-effective protection scaled to your size, not an enterprise price tag.
- Meets Cyber Insurance Requirements: insurers increasingly mandate centralized logging and 24/7 monitoring, this checks that box directly.
- No Hardware Costs: cloud-native architecture means no servers to buy to run your SIEM.
For Enterprises and Co-Managed IT
- Force Multiplier: we handle log monitoring and Tier 1 analysis, freeing your team for Tier 2/3 response and strategy.
- Advanced Threat Hunting: our CISSP-led SOC actively hunts for threats rather than waiting for alerts.
- Custom Integration: we integrate with complex cloud environments and custom applications your team already uses.
Our Process
- Â Free Cyber Security & AI Risk Assessment: a no-obligation review of your current logging and visibility gaps.
- Connect: we ingest logs from your firewalls, servers, endpoints, and cloud services.
- Tune: correlation rules get applied and refined to your specific environment.
- Monitor: our SOC watches 24/7/365, investigating and escalating real threats.
- Review: coverage gets reassessed as new systems and applications get added.
Log Coverage That Grows With Your Environment
Every new server, cloud application, or business system you add is a new log source, and a source that never gets connected to the SIEM is a blind spot no one notices until it matters.
We review your log source inventory on a regular basis, not just at initial setup, so a new system gets folded into monitoring as part of routine business, not forgotten until an audit or an incident finds the gap first.

Mapping to Compliance
- PCI DSS: supports Requirement 10 (track and monitor access to cardholder data), including daily log review and one-year retention.
- HIPAA: supports Audit Controls (§164.312(b)) by recording and examining activity in systems containing ePHI, with audit trails ready for OCR investigations.
- SOC 2 Type II: supports CC7.2, monitoring system components for anomalies indicative of malicious activity, with the evidence auditors need.
- CMMC 2.0: aligns with NIST SP 800-171 Audit and Accountability controls, providing the logging and alerting required for Level 2 compliance and above.
- CIS Control 8, Audit Log Management: we handle the full log lifecycle, establishing the process, collecting logs, ensuring secure storage, and standardizing time synchronization for accurate correlation.
Computerease Managed SIEM vs. DIY SIEM Software
| Â | Computerease Managed SIEM | DIY SIEM Software |
Setup | Turnkey, we build parsers and rules | Months of configuration before it’s useful |
Who’s watching | 24/7/365 SOC | Whoever on your team has time |
False positive tuning | Handled by our team continuously | Your problem to solve |
Cloud coverage | Microsoft 365, Azure, AWS, Google Workspace built in | Requires custom integration work |
Cost | Predictable monthly fee | Software cost plus staff time to run it |
What Real Log Visibility Really Means
Managed SIEM is not really about a dashboard full of charts. It is about being able to say, after something goes wrong, exactly what happened, when, and how, instead of guessing.
Our goal is not to bury you in alerts. It is to make sure the one alert that actually matters gets caught and acted on immediately, so a real incident gets a fast, informed response instead of getting lost in noise no one had time to review.

Questions Businesses Ask Us
SIEM is the tool that collects and organizes data. The SOC is the team that analyzes it. A SIEM without a SOC is a security camera with no one watching the monitor.
Yes. Attacks are automated and target vulnerabilities, not business size, and most cyber insurance policies now require centralized logging and monitoring to maintain coverage.
Pricing is based on the number of devices or data volume, significantly less than hiring a single full-time security analyst
Yes. We ingest logs from Microsoft 365, Azure, AWS, Google Workspace, and SaaS applications for a unified view of your hybrid environment.
No. We apply a large library of correlation rules to your environment immediately, and build custom rules for anything specific to you. No query language to learn, no parsers to manage.
Firewall logs and events stream directly into the SIEM platform, where our SOC correlates them with data from your endpoints and cloud applications for a unified, cross-infrastructure view.
