Core Security Layers: Firewalls, Antivirus, and MDR

In today’s ever-evolving threat landscape, protecting your business requires more than just a single layer of defence. Core security solutions such as Firewalls, Antivirus (AV), and Managed Detection and Response (MDR) form the backbone of a robust security strategy. These essential layers provide IT managers and business owners with the tools they need to safeguard their digital assets, ensuring operational continuity and peace of mind.

Why Firewalls Are Critical for Network Security

Firewalls are your organisation’s first line of defence, acting as a barrier between your internal network and external threats. By monitoring and controlling incoming and outgoing network traffic, firewalls prevent unauthorised access, safeguard sensitive data, and ensure compliance with security policies.

Key Features of Firewalls:

  • Traffic Filtering: Identifies and blocks malicious traffic while allowing legitimate connections.
  • Intrusion Prevention: Detects and prevents sophisticated cyberattacks targeting your network.
  • Application Control: Restricts or permits application usage based on organisational policies.
  • Advanced Threat Protection: Shields against malware, ransomware, and zero-day exploits.

Firewalls play a pivotal role in securing the perimeter of your network, providing a proactive defence against cyber threats.

The Importance of Antivirus Software

Antivirus software is an essential layer of endpoint protection, designed to detect, prevent, and remove malicious software from devices. With the rise of sophisticated malware, ransomware, phishing attacks, and zero-day threats, a strong antivirus solution is crucial for maintaining the integrity of your organisation’s systems.

Key Features of Antivirus Solutions:

  • Real-Time Scanning: Continuously monitors files and applications for malicious activity.
  • Heuristic Analysis: Identifies new and unknown threats by analysing suspicious behaviours.
  • Automatic Updates: Ensures protection against the latest malware strains.
  • Endpoint Management: Centralised control for IT managers to oversee all protected devices.

Antivirus software is an indispensable tool for protecting your endpoints and preventing malicious code from compromising your network.

Managed Detection and Response (MDR): Elevating Security

MDR takes security to the next level by combining advanced threat detection with human expertise. This service provides continuous monitoring, proactive threat hunting, and rapid response to incidents, ensuring that even the most sophisticated attacks are mitigated effectively. With MDR, IT managers and business owners gain access to a team of over 500+ threat detection and response experts, delivering unparalleled expertise to safeguard your organisation.

Key Features of MDR:

  • 24/7 Monitoring: Round-the-clock surveillance to detect and respond to threats in real time.
  • Threat Hunting: Actively searches for potential vulnerabilities and threats within your network.
  • Incident Response: Provides expert guidance and remediation during a security incident.
  • Comprehensive Reporting: Offers actionable insights to enhance your overall security posture.

MDR fills the gaps in traditional security measures, providing organisations with a robust, managed service to combat advanced cyber threats.

The Security Onion: A Layered Approach

A strong security strategy is built on multiple layers of defence. At ADM, we refer to this as layers of our recommended “security onion.” This approach ensures that no single point of failure compromises your organisation’s safety.

Core Layers of the Security Onion:

  • Scanning, Testing, and Monitoring: Ensure continuous visibility and proactive threat detection.
  • Identity Protection: Secure user accounts with robust authentication measures.
  • Email Filtering: Block malicious emails and phishing attempts before they reach inboxes.
  • DNS / Ransomware Protection: Safeguard against threats with advanced detection and response capabilities.
  • Backups: Maintain secure and reliable data recovery solutions.
  • Firewalls: Protect your network perimeter and filter traffic.
  • Virus Protection: Defend endpoints from malware and viruses.
  • Patch Management: Keep systems up to date to eliminate vulnerabilities.
  • Application Control: Manage and restrict access to unauthorised applications.
  • Policies and Training: Educate employees with security awareness training and enforce robust policies.

By adopting a layered security approach, organisations can create a resilient defence system that adapts to evolving threats.

Key Benefits of a Strong Security Posture

Enhanced Protection: Safeguard your organisation against a wide range of cyber threats.

Business Continuity: Minimise downtime and ensure operational resilience.

Regulatory Compliance: Meet industry standards and avoid penalties for non-compliance.

Improved Productivity: Reduce disruptions caused by malware or other security incidents.

Scalable Solutions: Security measures that grow with your business.

        Frequently asked questions - Firewalls, Antivirus & MDR

        What’s the difference between antivirus, firewalls, and MDR?

        Antivirus detects and removes known malware from devices. Firewalls act as gatekeepers, controlling traffic in and out of your network. Managed Detection and Response (MDR) goes further – using 24/7 monitoring, AI, and expert analysts to detect and respond to suspicious behaviour in real time. Together, these form key layers in ADM’s Security Onion approach to cybersecurity.

        Do you offer fully managed antivirus and firewall services?

        Yes. ADM provides managed endpoint protection, firewall configuration, ongoing updates, and monitoring – all fully supported by our in-house security team. We work with trusted solutions like Sophos and WatchGuard, and tailor everything to suit your business size, compliance needs, and infrastructure.

        What does a Managed Detection and Response (MDR) service include?

        Our MDR solution combines real-time threat detection, 24/7 expert analysis, and immediate response. With dozens of analysts monitoring global threats, suspicious behaviour is flagged and contained before it becomes a breach. MDR is especially valuable for identifying sophisticated threats that traditional antivirus tools might miss.

        Can ADM manage our firewall and antivirus policies across multiple sites?

        Absolutely. We work with multi-site organisations, managing firewall rules, antivirus policies, and security updates from a central platform. Whether you have remote workers, branch offices, or a hybrid setup, we ensure consistent, secure coverage across every location and device.

        How do you choose which security tools to recommend?

        We partner with industry-leading vendors like Sophos for antivirus and WatchGuard for firewall solutions – but we don’t take a one-size-fits-all approach. Instead of using everything from a single vendor, we select best-in-class technologies for each security layer. That way, you get the right combination of protection, performance, and value – without vendor bias. Our long-term partnerships allow us to deliver excellent support and pricing, tailored to your environment.

        Is your MDR solution suitable for SMEs as well as larger organisations?

        Yes. Our MDR service scales from small teams to complex enterprise environments. We make sure you get the right level of visibility, control, and expert support – without overcomplicating things or overcharging. Many SMEs choose MDR as a cost-effective way to access enterprise-grade security without the internal overhead.

        Why choose ADM for managed antivirus, firewall, and MDR support?

        ADM has been protecting businesses across Kent since 1984. Our clients trust us for honest advice, transparent pricing, and high-quality service – not contract lock-ins. With over 50 engineers, a 99.7% satisfaction score, and a long track record of delivering tailored cybersecurity, we’re here to protect what matters most to your business.
