Network Security Introduction

Network Security is the concept of protecting devices which are talking to each other. It ensures they are having legitimate conversations which are not being hijacked by malicious threats.


Our Network Security solution targets a variety of threats and stops them from entering or spreading on your network. It includes both hardware and software technologies.

Building a Network Security solution

Our Network Security solution is based upon three main elements which are highlighted below.

Software Defined Access (SD Access)

Software-Defined Access is the industry’s first intent-based networking solution for the Enterprise built on the principles of Cisco’s Digital Network Architecture (DNA). SD-Access provides automated end-to-end segmentation to separate user, device and application traffic without redesigning the network. SD-Access automates user access policy so organisations can make sure the right policies are established for any user or device with any application across the network. This is accomplished with a single network fabric across LAN and WLAN which creates a consistent user experience anywhere without compromising on security.

Encrypted Traffic Analytics

Encrypted Traffic Analytics focuses on identifying malware communications in encrypted traffic through passive monitoring, the extraction of relevant data elements and supervised machine learning with cloud based global visibility.

Cisco FirePOWER

Block more threats and quickly mitigate those that do breach your defences with the industry’s first threat-focused NGFW. Cisco’s Firepower NGFW appliances combine their proven network firewall with the industry’s most effective next-gen IPS and advanced malware protection. All so you can get more visibility, be more flexible, save more, and protect better. A user agent monitors up to five Microsoft Active Directory servers and reports logins and logoffs authenticated by Active Directory. The Firepower System integrates these records with the information it collects using traffic-based detection on managed devices.

How we can help you

Working with us

The rate of change in the modern technology landscape is greater now than it has been for the last 20+ years. This makes it critical for companies who want to remain competitive to remain flexible in their ability to consume new technologies. The further a company falls behind, the greater the effort required to catch-up to the current benchmark.


We work closely with companies to build platforms and roadmaps. Our solutions maintain a good balance between remaining flexible enough to incorporate new technologies that can advance the business, whilst ensuring that a core focus remains on delivering tangible outcomes.


Throughout the engagement process, we will provide ongoing consultation and feedback that helps determine which technologies to look out for, where they can be a good fit and how they can be incorporated into the environment in question.
