Managed Security Service Provider for Financial Services

Most financial services firms reach a point where managing a telco contract for connectivity and a separate security provider for threat monitoring creates more cost and complexity than it solves. The telco does not understand the security layer. The security provider does not own the network. When something goes wrong across both, each vendor points at the other. Consolidating under a single managed provider means one contract, one support team, and one view across your network and security environment. MCK manages both under one service agreement. Your network infrastructure, connectivity across locations, threat detection, and incident response are all handled by the same team watching the same environment. The transition is staged so your operations are not disrupted, and your existing hardware is assessed before any replacement is recommended.

FCA, SEC, SOC 2, and NIST frameworks expect firms to produce documented evidence across several areas: who accessed which systems and when, what changes were made to network configurations, how security incidents were detected and handled, and what controls are in place to restrict access to sensitive data. This includes hardware-based access management controls such as MFA devices, smart card systems, and privileged access management tools, all of which need to be logged and auditable. Zero-trust security architecture, where access is verified continuously by identity and role rather than assumed because a device is on the network, is increasingly referenced in regulatory guidance as the expected standard. The evidence trail needs to cover all locations and all users, not just head office. Most financial services firms on standard telco or general IT contracts cannot produce this at short notice because centralised logging was never configured. MCK builds audit-ready logging, zero-trust access controls, and NIST-aligned security configurations into the service from the start. Monthly reports cover network activity, security events, and access records across all your sites. When an auditor asks, the evidence is already there.

Alert volume is one of the biggest operational problems for financial services firms without an in-house security team. A SIEM or monitoring tool running without active management generates hundreds of alerts a day, most of which are noise. Without someone trained to triage them, real threats get buried. MCK's SOC handles this triage function on your behalf. CORTAI, the independent AI-driven platform powering MCK's detection capability, correlates signals across your network, endpoints, and cloud environment to separate genuine threats from false positives. The SOC team investigates alerts, confirms which represent real risk, and acts on confirmed threats without waiting for you to raise a ticket. Your team only hears about what matters and what was done about it.

PCI DSS applies to any business that stores, processes, or transmits payment card data, regardless of size. For smaller financial firms, the core requirements break down into four practical areas: network segmentation (isolating payment systems from the rest of the network), access controls (restricting who can reach cardholder data and logging all access), encryption (protecting card data in transit and at rest), and regular testing (vulnerability scans and penetration tests on a defined schedule). The most common failure point for smaller firms is network architecture. A flat network where payment systems, staff workstations, and guest Wi-Fi share the same segment places the entire network in PCI audit scope, which increases both compliance cost and risk with every device you add.

The answer for most financial services SMEs is a fully managed service that takes on both the network and security function without requiring internal staff to own it. Security budgets across the industry are flat or shrinking while the scope of responsibility keeps growing. A managed service converts unpredictable capital expenditure into a fixed monthly cost that covers network monitoring, threat detection, and incident response. MCK manages your connectivity, network monitoring, threat detection, and incident response as a service. Your advisors, compliance team, and operations staff are not expected to handle IT or security incidents. When a circuit fails, MCK's NOC responds. When a threat is detected, MCK's SOC contains it. For financial services firms at 20 to 200 staff, MCK replaces the need to hire a network engineer and a security analyst, and covers both disciplines around the clock.
