Managed Security

The problem

Most breaches start where no one is looking.

Perimeter

Exposed Attack Surface

Firewalls age, rules drift, and ports get opened for a project and never closed. Each gap is an unlocked door an attacker can walk through. Most SMEs have no one checking the perimeter every day.

Monitoring

No Around-the-Clock Coverage

Attacks land at night and over weekends, when in-house IT is offline. A threat can move through your network for days before anyone notices. The longer it stays hidden, the more it costs to remove.

Alert fatigue

Too Many Tools, Too Much Noise

Most SMEs run a stack of security tools that do not talk to each other. Each one fires its own alerts, and the real threat gets buried in the noise. Stretched IT teams cannot triage thousands of warnings a day.

Endpoints

Unprotected Endpoints

Laptops, remote devices and personal hardware sit outside the office firewall. They are the first place ransomware and infostealers try to land. Without monitoring on every device, one infected endpoint can reach the whole network.

Exposure

Unknown Vulnerabilities

New software flaws appear faster than small teams can patch them. Without continuous scanning, you cannot see which weaknesses attackers will target first. Unpatched systems stay exposed for weeks or months.

Compliance

Compliance and Audit Pressure

Customers and regulators expect proof of security controls, not promises. Preparing for HIPAA, PCI-DSS, SOC 2 or PIPEDA audits pulls your team off real work. Evidence is scattered across tools and hard to produce on demand.

What we manage

One security service that covers every layer.

MCK runs your security operations as one service: prevention, detection, response and compliance, managed by our team and powered by CORTAI. You get the coverage of an enterprise security team without building one in-house.

Your perimeter, hardened, monitored and kept up to date.

MCK deploys and manages your Fortinet NGFW end to end. We set the policy, tune the rules, apply updates and watch the traffic, so the perimeter stays closed without pulling your team into firewall admin.

Fortinet NGFW deployment, configuration and policy management
Daily rule review and change control, with every change logged
Intrusion prevention tuned to your environment
Application control and web filtering by policy
Firmware and signature updates applied and tested

Threat detection on every device, with fast containment.

EDR puts a sensor on every laptop, server and remote device to spot malicious behavior the moment it starts. CORTAI flags the activity and can isolate an infected device in seconds, before it spreads. This is threat detection and response, not desktop support.

What we manage

Behavioral threat detection on laptops, servers and remote devices
Automatic containment to isolate a compromised device in seconds
Ransomware and infostealer detection based on behavior, not signatures alone
Rollback of malicious changes where the platform supports it
Investigation of every confirmed alert by the SOC team
Device telemetry fed into the SIEM for full-environment context
Coverage for remote and personal devices outside the office network
Monthly endpoint threat and coverage report

60-second auto-containment

Behavior-based detection

Know your exposure before attackers find it.

MCK scans your environment continuously to find weak points, then ranks them by real-world risk so you fix what matters first. You get a clear, prioritized list of what to patch, not a raw dump of thousands of findings.

What we manage

Continuous scanning of your network, servers, endpoints and cloud
Risk-based prioritization by exploitability and exposure
External attack surface scanning of internet-facing systems
Patch guidance with clear owners and timelines
Validation rescans to confirm a fix actually closed the gap
Tracking against your compliance and audit requirements
Alignment with CISA Known Exploited Vulnerabilities where relevant
Monthly exposure report with trend over time

Audit-ready evidence all year, not just at audit time.

MCK maps your security controls to the frameworks you are accountable to, then keeps the evidence current as you operate. When an audit comes, the proof is already gathered, so your team is not scrambling to pull reports the week before.

What we manage

Control mapping to HIPAA, PCI-DSS, SOC 2 and PIPEDA
Continuous evidence collection from your security tools
Gap assessments against each framework you are subject to
Policy and procedure templates aligned to your obligations
Audit-ready reporting available on demand

Replace over-trusted VPN access with least-privilege control.

ZTNA gives each user access only to the specific apps they need, checked by identity and device posture every time. Unlike a VPN, it never drops users onto the wider network, so a stolen login cannot roam. MCK sets the policies, connects your apps and manages access as people join, move and leave.

What we manage

Identity-based access policies for each app and user group
Device posture checks before access is granted
Per-application access instead of full network access
Replacement of legacy VPN for remote and hybrid staff
Access tied to your identity provider, with SSO and MFA
Continuous verification, not just a one-time login
Access activity fed into the SOC and SIEM
Access changes managed as staff join, move and leave

Least-privilege access

Identity and device verified

Know where your sensitive data is, and stop it walking out.

DLP finds sensitive data across your environment and sets rules for how it can be used, shared and moved. It blocks risky actions, such as emailing customer records to a personal account or copying files to an unmanaged drive. MCK builds the policies around your data and the rules you must meet, then tunes them so work is not disrupted.

What we manage

Discovery and classification of sensitive data across endpoints, email and cloud
Policies controlling how data is shared, copied and sent
Blocking or alerting on risky transfers, with context for the SOC
Coverage for email, web uploads, removable media and cloud apps
Rules mapped to HIPAA, PCI-DSS and other obligations
Protection for data on remote and personal devices
Incident review when a policy is triggered
Ongoing tuning to cut false positives

Frequently asked questions

Managed Security Services FAQs

What is managed security services?

Managed security services are security operations run for you by an outside provider, instead of an in-house team. The provider monitors your systems, detects threats, responds to incidents and manages compliance, around the clock. You get enterprise-level security as an ongoing service, without hiring and running a security team yourself.

How are managed security services beneficial for your business?

They give you 24/7 protection that most SMEs cannot staff or afford to build alone. Threats are caught and contained faster, your team stays focused on the business, and your security keeps pace as you grow. You also get predictable monthly costs instead of large upfront spend on tools and hires.

What is the difference between managed security services and cybersecurity services?

Cybersecurity is the broad practice of protecting systems and data from attack. Managed security services are how that protection is delivered: an outside provider operates it for you, day to day, as a service. In short, cybersecurity is the what, and managed security services are the who and the how. MCK runs cybersecurity as an operational service, rather than selling you tools to manage yourself.

What is a managed security service provider?

A managed security service provider, or MSSP, is a company that operates security for other businesses as a service. That covers monitoring, threat detection, incident response and compliance, delivered by a dedicated team and platform. MCK is a managed security service provider for SMEs across the USA, Canada and the UK.

What is included in managed security services?

MCK's managed security covers your full security operation: managed firewall, a 24/7 security operations center, SIEM and log management, endpoint detection and response, vulnerability management and compliance support. Each part feeds the others, so a signal on one device is checked against everything else in your environment. You choose the scope, and MCK runs it.

What kind of business needs managed security services?

Any SME that holds sensitive data, must meet compliance rules, or cannot watch its systems around the clock is a strong fit. That includes healthcare, financial services, legal, hospitality and other businesses from roughly 20 to 200 staff. If a breach would disrupt your operations or your reputation, managed security is worth it.
