Secure Network Services
Securing a modern network requires a multi-layered approach. Endpoints, email, web applications, cloud platforms, firewalls, and directory services all represent potential attack surfaces — and attackers only need to find one weak point.
Technicalities brings deep, hands-on expertise across each of these layers, with solutions designed to limit risk across your entire environment — not just the most obvious entry points.
Network security isn’t a single product or a one-time configuration — it’s a continuous practice. We help businesses build layered defences that cover every part of their environment, from the device on a desk to the data in the cloud.
Protect Every Device on Your Network
Endpoints — laptops, desktops, mobile devices — remain the most common entry point for attackers. Traditional antivirus is no longer enough. Our endpoint managed services platform combines patch and update management with a modern Endpoint Detection and Response (EDR) solution, providing protection against both known and emerging threats.
Our EDR platform uses AI to detect behavioural indicators of attacker activity — identifying threats in near real time, not after the damage is done. It also supports threat hunting using the MITRE ATT&CK framework, mapping behavioural patterns across your environment to detect and respond to anomalous activity before it escalates.
Stop Threats at the Inbox
The majority of cyber attacks begin with an email. We partner with Proofpoint — an industry-leading email security platform — to protect your organisation against phishing, spam, malware, and impostor threats.
Proofpoint detects text, image, and attachment-based threats, including those that bypass standard filters. Depending on your subscription level, it can also deliver:
- Spam and phishing detection with industry-leading accuracy
- Malware and non-malware threat protection
- URL and attachment sandboxing
- Policy-enforced encryption and data loss prevention
- Impostor email detection with dynamic classification
- 24×7 emergency inbox in the event of an outage
Eliminate data storage constraints and meet legal and regulatory obligations with Proofpoint’s 10-year cloud archive.
Ensures you stay protected, compliant, and audit-ready.
Protect Your Web Presence
Businesses focus heavily on protecting their internal networks — but the websites, web stores, and web applications they run are equally exposed. Web security covers the detection, prevention, and response to threats targeting your public-facing digital assets.
A Web Application Firewall (WAF) is the first line of defence, monitoring and filtering traffic between your application and the internet. WAFs provide protection against cross-site scripting, SQL injection, cross-site forgery, file inclusion attacks, and more — threats that standard network firewalls are not designed to catch.
Your Cloud Is Not Automatically Secure
Cloud adoption has accelerated the pace of business — but it has also created a common misconception: that cloud providers secure everything in their environment. They don’t. Cloud providers secure the infrastructure itself; the security of your data and applications within that infrastructure remains your responsibility.
Whether you operate on a private, public, or hybrid cloud, your security posture needs to follow your workloads wherever they are. Our security methodology is consistent across all cloud environments, and our toolset is selected with cloud-first architectures in mind — ensuring your critical assets are protected regardless of where they’re hosted.
A Firewall Is Only as Good as Its Configuration
Almost every organisation has a firewall — but a poorly configured firewall provides little real protection. We regularly see businesses compromised through weak firewall policies that could have been prevented with proper rule design and access controls.
Technicalities provides a comprehensive firewall auditing service, reviewing your existing configuration for vulnerabilities and delivering a prioritised remediation report. Our engineers have experience across the three leaders in the Gartner® Magic Quadrant for Network Firewalls — Palo Alto Networks, Fortinet, and Check Point — as well as WatchGuard, SonicWall, and Sophos.
Firewalls Aren’t Set and Forget
As your network changes and attack techniques evolve, your firewall policies need to keep pace. Drawing on best practices from NIST, Mandiant, and leading firewall vendors, our engineers will reconfigure your firewall infrastructure to provide the highest level of protection against current attack methods.
Ask us about our managed firewall service — ongoing monitoring and hardening of your firewall infrastructure, so your defences stay current without placing the burden on your internal team.
Limit the Blast Radius of a Breach
Network segmentation divides your environment into smaller, isolated sections — each with strict controls governing who and what can access it. This prevents unauthorised users from moving freely through your network to reach financial records, customer data, or intellectual property.
Critically, segmentation also limits the damage if a breach does occur. Rather than giving an attacker free rein across your entire environment, a well-segmented network contains the impact to a small portion of your infrastructure. Our network engineers are specialists in segmentation design and implementation for businesses of all sizes.
Your Most Critical — and Most Targeted — System
Active Directory governs authentication across your entire organisation. It holds credentials, manages access rights, and controls who can reach every system and asset on your network. That makes it one of the highest-value targets for attackers — and a component used by close to 90% of businesses worldwide.
Most organisations run AD configurations with exploitable weaknesses, and review them only once a year — if at all. As AD changes constantly, manual monitoring is impractical. Technicalities has partnered with a world-leading AD security platform to provide continuous, automated protection:
- Discover and map existing weaknesses with step-by-step remediation guidance
- Continuously identify new vulnerabilities and misconfigurations as they emerge
- Receive real-time alerts with actionable remediation plans for active attacks
- Investigate incidents and hunt for threats across your AD environment
