Secure Access Service Edge
With the digital transformation of businesses, security is moving to the cloud. This is driving a need for converged services to reduce complexity, improve speed and agility, enable multi-cloud networking, and secure ‘the new SD-WAN-enabled architecture’ – Secure Access Service Edge (SASE).

Revolutionise your network security
What is SASE?
Secure Access Service Edge (SASE) allows an organisation’s users to securely access the cloud, while keeping the company’s cloud-based applications protected. SASE integrates network security and wide-area networking (WAN) into a unified, cloud-delivered service model.
It merges several technologies into a single platform, like web gateways, cloud access security brokers, firewall as-a-service, and zero-trust network access. These functions are delivered from the cloud and provided as a service by the SASE vendor.
The role of SASE in digital transformation
According to Gartner, traditional network security architectures, which place the enterprise data centre at the centre of network connectivity, fail to meet the dynamic access requirements of digital businesses.
Gartner advocates for consolidating networking and security-as-a-service capabilities into SASE. Secure access cloud services should not be constrained by company networks or limited by backhaul connections through corporate data centres, and SASE addresses these challenges by combining SD-WAN with Security Service Edge (SSE).
The key components of SASE:
Software-defined wide area networking (SD-WAN): Optimises connectivity between enterprise networks and cloud-based resources, ensuring efficient and reliable data transfer.
Secure web gateway (SWG): Protects users from web-based threats by enforcing security policies and filtering malicious traffic.
Cloud access security broker (CASB): Provides visibility and control over the use of cloud services, ensuring compliance with security policies.
Zero trust network access (ZTNA): Grants access to resources based on strict identity verification, regardless of the user’s location.
Firewall-as-a-service (FWaaS): Delivers firewall capabilities as a cloud service, protecting against network threats without the need for on-premises hardware.
Wherever you are on your SASE journey, CTC has the ideal solution for you.

Endpoint Detection & Response
Cyberattacks are becoming are common, advanced, and costly, highlighting the need for companies to adopt comprehensive cybersecurity strategies – strategies that involve detection and response capabilities that identify threats which circumvent security measures.
Identity and Access
Management (IAM)
Identity and access management (IAM) is a framework of business processes, policies, and technologies. Specifically, it facilitates the management of electronic/digital identities, and is essential for safeguarding your organisation’s sensitive data and critical functions – ensuring on authorised users can access these resources.
Unified Analytics Threat Management (UTM)
Unified threat management (UTM) is an information security (infosec) system that provides a single point of protection against threats, including viruses, worms, spyware and other malware, and network attacks. It combines security, performance, management and compliance capabilities into a single installation, making it easier for administrators to manage networks.
