Access Control Introduction

Access Control refers to the visibility of who and what is accessing your network. It ensures the right people are using the right devices, to access the right resources. This controls the spread of information and prevents unwanted visitors gaining access to your data.


This enables you to give certain access permissions to users based on the device they are using, or the time of the day, to reduce the chance of a breach.

Components of an Access Control solution

Our Access Control solution is based upon three individual pieces of Cisco security technology which are highlighted below.

Identity Services Engine (ISE)

A security policy management platform that automates and enforces context-aware security access to network resources. Identity Services Engine delivers superior user and device visibility to support enterprise mobility experiences and to control access. It shares data with integrated partner solutions to accelerate their capabilities to identify, mitigate, and remediate threats.

Stealthwatch Enterprise

Cisco Stealthwatch uses telemetry from existing network infrastructure for advanced threat detection, deeper forensics and simplified network segmentation. With industry-leading machine-learning and behavioural modelling, you can outsmart emerging threats in your digital business. Detect attacks that get past perimeter defences across the digital business. Detect malicious patterns in encrypted traffic. No decryption is needed with Cisco’s Encrypted Traffic Analytics technology and multilayer machine learning. Along with ISE, Stealthwatch delivers unmatched visibility and access control.

SD Access (Software Defined 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.

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.
