Ever since the outbreak of COVID-19 pandemic in 2020, businesses across the globe are forced to strengthen their cybersecurity measures to protect their data and networks. With huge number of organisations turning to work from home on a permanent or semi-permanent basis, strong networking is now necessary more than ever.

While organizations spent a better half of the year contemplating what strategy to implement better work environments, India and many parts of the world going under COVID-induced lockdown in 2020 resulted in the C-Suit looking for the right networking solutions which are now the emerging networking trends of 2021.

Though the number of coronavirus cases continue to decline in India, companies are still contemplating returning to office. Remote working is now a part of the work environment. Even new recruits are being given an option to work remotely by many. At a time like this, technology has and will be the core enabler of the transition that many organizations are witnessing in the post-pandemic world. 2020 has been unusual and this has led to technology gaining inroads into all sectors from education to healthcare. Remote working, hybrid workforce, cloud transitions are all necessary to support business continuity and networking is needed to achieve success.

So what are the emerging networking trends of 2021?

  • Network Automation

Today, organizations have both traditional and cloud-native applications, to manage these applications with speed, agility and consistency network automation is most preferred. According to a recent survey, it is said that network automation has been 70 percent top technology trend due to the pandemic as organizations needed advanced technologies to help them navigate the sudden change.

  • Zero Trust

Traditional security parameters are time and again proved to be ineffective with more high-tech targeting tactics. Zero trust helps organizations fight such threats at micro-level with authentication of access requests at every point within a network. By2027 at 19.71% CAGR, the zero trust security market is projected to reach $94.35 Bn and this is the indication of the important role zero trust is to play.

  • Internet of Behaviors (IoB)

Gartner predicts that by 2023 individual activities of 40% of the global population will be tracked digitally to influence our behavior. The interconnection of devices resulting in a vast variety of new data is what exactly IoB refers to. To manage such a vast variety of data a strong network solution is required which would avoid the websites or the organization’s platform from collapsing.

  • SD-WAN

Software-defined wide area network (SD-WAN) is a virtual WAN architecture that simplifies the management of branch network connections and enables faster cloud connectivity. While the demand for SD-WAN decreased a bit in 2020, the demand is predicted to increase in the coming years showcasing the constantly shifting of the work process from traditional to the cloud.

  • Cybersecurity Mesh

To achieve scalable, flexible and reliable security, the concept of cybersecurity mesh is popular. For intensified remote working like the current times, there is a need to protect data from external and sometimes internal threats and cybersecurity mesh is the right approach.

  • IoT and Network Edge

The point at which the enterprise-owned network connects to a third-party network is known as the network edge. With the overflow of data, many data centers and devices experience strain. To remove this strain from DCs, the network edge physically moves the computation part from DCs to the edge of the network. The edge computing network architecture can conserve network resources by offloading network traffic, thereby reducing network latency and bottlenecks.

  • SASE

Secure Access Service Edge (SASE) is useful for remote working as organizations revamped their network architecture to enable remote working, IoT endpoints and teleworkers. A distributed workforce with a decentralized infrastructure needs a different security posture as part of that architecture and SASE is emerging as an appropriate solution.

  • Hybrid Work Model

The hybrid work model existed before the pandemic hit the world, however, it became necessary and relevant with the onset of the pandemic. The key to the hybrid work model is digitalization and for a strong digitalization process, networking is of utmost importance. For a strong hybrid work environment the network products and services should be updated and state-of-the-art, hence making the work model successful with reduced risk factors.
