Cybersecurity isn’t a one-time project—it’s an ongoing program that reduces risk every month. Acumen delivers managed Cybersecurity for St. Louis organizations that need practical protection, clear reporting, and fast response when something looks wrong.
We work especially well with engineering firms, professional services, and large nonprofits where uptime, client data, and account security matter. Many of the services below are also included in the Acumen Managed Services package alongside Managed IT Services.

Block phishing and malware domains before users can connect. We enforce DNS policies across the network to reduce ransomware and command-and-control traffic.
Close security holes fast with managed patching for Microsoft and key third-party apps. We schedule, deploy, and verify updates to reduce risk and downtime.
Monthly internal and external vulnerability scans with prioritized remediation recommendations.
Virtual CISO (vCISO) guidance from an experienced security leader—risk assessments, security strategy, policies, compliance support, and executive-ready reporting.
Early-warning canary files detect suspicious encryption activity and alert Acumen’s NOC immediately.
Acumen provides managed Cybersecurity services in St. Louis for organizations that need protection that’s maintained, monitored, and improved over time. Instead of deploying tools and hoping they’re configured correctly, we operate Cybersecurity as a program with clear ownership and consistent follow-through.
That matters because most incidents don’t happen due to a single missing product. They happen because of gaps: a workstation that didn’t patch, an account with weak authentication, an exposed credential that wasn’t discovered, or an alert that no one investigated. Therefore, our focus is simple: reduce exposure, detect earlier, respond correctly, and show measurable progress month after month.
Different industries have different failure modes. Engineering firms often need stable standards, predictable access controls, and protection for project data. Professional services firms need strong identity protection, reliable endpoints, and defensible client security posture. Large nonprofits typically need practical improvements that fit budgets while still meeting board and donor expectations.
Because of that, our approach combines operational reliability with security discipline. In other words, we build controls that your team can live with—then we maintain them so they don’t drift.
When you partner with an MSP for Cybersecurity, the value is not the tool list—it’s what happens every month. Depending on your environment and package, you can expect deliverables such as:
Monitoring + response workflow: alerts are reviewed, triaged, and escalated with containment steps when needed
Patch management with verification: updates are managed and exceptions are identified so “silent risk” doesn’t linger
Vulnerability visibility + prioritized remediation: findings are organized by exploitability and business impact, not dumped into a backlog
Credential exposure review: compromised credentials are flagged and response steps are guided (password resets, MFA review, access review)
Threat intelligence guidance: emerging threats are translated into practical mitigations when relevant
Security program guidance: vCISO-style prioritization, policy direction, and executive-ready reporting
As a result, you get both protection and a plan—plus documentation that supports leadership oversight and external requirements.
To keep Cybersecurity predictable and accountable, we use a repeatable cycle:
Baseline and confirm what’s protected, what’s missing, and what should be addressed first
Harden and standardize configurations so your environment stays consistent over time
Monitor and investigate events that indicate real risk, while reducing alert noise
Contain and remediate threats safely, then document actions taken and improvements made
Review and improve with a prioritized plan so risk declines over time—not just “changes shape”
This process is intentionally boring. That’s the point: security should be steady, not reactive.
Endpoint Protection, Threat Detection, and Response
Endpoints are where many incidents start. Therefore, we prioritize endpoint visibility, detection, and response. When suspicious activity appears, we validate it, investigate the context, and take action when required.
If an issue is confirmed, response may include isolating an affected system, guiding credential resets, reviewing access, and coordinating remediation steps. Afterward, we document what happened and adjust controls so the same pattern is less likely to recur.
Vulnerability Scanning and Remediation Planning That Actually Gets Done
Scanning alone doesn’t reduce risk. Instead, it creates a list—sometimes an overwhelming one. That’s why we pair vulnerability insight with a remediation plan that prioritizes:
what is most likely to be exploited
what affects critical systems and user access
what can be fixed quickly for immediate reduction in risk
what should be scheduled as a planned improvement project
Consequently, you get progress you can see, not reports that pile up.
Patch Management and Update Verification
Attackers routinely exploit known vulnerabilities, which is why patching and verification remain core controls. We manage updates and focus on exceptions—systems that didn’t patch successfully or need a special approach. In addition, we align patching with stability so you get security without constant disruption.
Over time, consistent patch management reduces exposure to ransomware, privilege escalation, and remote-code vulnerabilities that commonly drive business-impact incidents.
Phishing Reduction Through Web/DNS Controls and Account Hardening
Phishing is still a daily threat, so prevention needs multiple layers. Web and DNS protections help prevent connections to known malicious infrastructure. Meanwhile, account controls and monitoring help reduce the blast radius if a user clicks or credentials are exposed.
In other words, the goal is not perfection—it’s reducing the probability of compromise and catching issues quickly when prevention fails.
Dark Web Monitoring and Credential Exposure Response
Credential exposure is common and often invisible. Therefore, we monitor for compromised emails and passwords appearing in known breach sources. When an event is identified, we help you respond quickly—reset passwords, enforce MFA where needed, and review access so the issue doesn’t become an account takeover later.
vCISO Guidance, Policies, and Security Roadmaps
Technology controls are only part of Cybersecurity. You also need a plan that leadership can understand. That’s where vCISO guidance helps: prioritization, policy direction, and reporting that translates technical work into risk reduction.
For example, we can help you build a roadmap, maintain a security baseline, and prepare documentation that supports audits, client security questionnaires, and cyber insurance renewals.
Cybersecurity for St. Louis Businesses (Local Expectations)
St. Louis organizations increasingly face vendor assessments and insurer requirements. Because of that, we focus on controls you can explain and defend, not just tools you can list. In addition, we help you organize documentation so renewals and questionnaires are less disruptive.
If you need a local MSP that can own the security program—monitoring, response, remediation planning, and ongoing improvement—we can help.
Do you offer Cybersecurity without full managed IT services?
In many cases, yes. However, the best approach depends on your environment and goals. We’ll review what you have and recommend an option that’s supportable and measurable.
What happens when an alert fires?
First, we triage the alert and confirm whether it’s real. If it is, we contain the issue when needed, then remediate and document actions taken. Afterward, we adjust controls so repeat incidents are less likely.
Will this help with cyber insurance and client security questionnaires?
Yes. We help implement and document controls commonly requested by insurers and vendor/security programs. We can also help map your controls to the questions being asked so responses are consistent.
How fast can we get started?
Typically, we begin with a baseline review and a prioritized plan. Then we validate controls and ensure monitoring and response workflows are in place. From there, we improve security steadily over time.
