What is Network Security?
Network security is critical. With the rise of digital transformation, the threats to network security have escalated, posing potentially devastating consequences as more processes and applications are moved online. This shift creates an ideal environment for malicious activities, emphasising the importance of maintaining a robust boundary between internal networks and the outside world.
As networks expand in size and complexity, so does the risk of cyber attack. In this landscape, network security plays a crucial role in safeguarding the integrity of network infrastructure, resources, and traffic. By implementing robust network security measures, organisations can mitigate the financial and operational impacts of cyber breach, ensuring the resilience of their digital operations.
Types of Network Security?
Next-Generation Firewall (NGFW) and Intrusion Prevention System (IPS) technologies provide the first line of defence against external threats to your network. The perimeter is changing, and firewalls are bombarded with ever-changing threats. IPS is a crucial tool to monitor traffic and take immediate action to stop unwanted visitors from getting in. You need the latest firewall technology, combined with a comprehensive
management service that includes the capability to analyse, prioritise, and resolve issues so that threats can be quickly addressed.
Keeping unauthorised users and devices out of your organisation’s wired and wireless network is essential. But what is access networking?Access networking refers to the infrastructure and technology that enables the connection between end users and your immediate service providers. It plays a crucial role in modern telecommunications by facilitating rapid data transfer and cost-effective communication.
We can help you with the most effective network access control (NAC) to restrict access to only those devices that are approved and compliant with your organisation’s security polices, limiting devices to access only what they need when they need it.
Let’s explore how our access networking solutions can help revolutionise your network management and enhance your cyber security posture.
Distributed Denial of Service (DDoS) attacks, where a network is bombarded with traffic from multiple sources, can cause devastation to Internet-facing services. Their aim is to cripple online services, compromise personal data, steal credit card data, deface brands, or even act as a smokescreen for other attacks. It’s no secret that DDoS attacks are rising in frequency across the UK, and all businesses – regardless of size or industry – are potential targets.
SASE consolidates networking and security functions traditionally delivered using multiple separate solutions into a single, fully-integrated cloud service. Our SASE offering combines SD-WAN, cloud access security broker (CASB), secure web gateway, cloud firewall and multi-factor authentication (MFA) to simplify how organisations manage and secure their networks, users, apps, and devices using a zero-trust approach.

A zero- trust approach
Gone are the days when networks were simple and centralised, safely enclosed within an organisation’s walls, where once someone was inside, they were trusted implicitly. This was the foundation of traditional security – a fortress mentality aimed at defending the perimeter while assuming the interior was secure.
But the digital landscape is transforming rapidly. The push towards digital transformation and the adoption of hybrid cloud technologies have profoundly reshaped our networks. They’re no longer confined to a single location. Instead, they stretch across cloud platforms, integrate on-premises data centres, and reach out to remote workers and devices everywhere, from smartphones to the burgeoning Internet of Things (IoT).
In this new, complex landscape, the old approach of perimeter defence simply doesn’t cut it anymore. Recognising this shift, network and cyber security professionals are moving decisively towards a zero-trust network security model. Zero trust does away with the outdated belief in implicit trust. It operates on a verify-first basis, necessitating strict authentication and authorisation for every access attempt, no matter where it comes from within or outside the organisation. It’s about giving the minimum access needed to complete a task, and not a bit more, then revoking that access immediately afterwards.
Our cyber and network defence solutions stand at the forefront of zero- trust, using leading-edge analytics and an extensive array of data sources to slash the time it takes to detect threats from months down to hours. Our cutting-edge technology provides instantaneous threat detection and resolution, delivering unmatched security coverage for your digital network.
Embrace a more secure future with our zero-trust solutions. Reach out to us to discover how we can enhance your digital defence, ensuring your network remains robust against evolving threats.
