Why is Microsegmentation Becoming a Popular Cyber Security Concept?

As the internet progresses, so too do the dangers that come with it. Ever since businesses moved online, cybersecurity has been a critical issue.

According to recent statistics, cybercrime is projected to cost the world $10.5 trillion annually, and just this year, a report found that nearly a quarter of all US companies have faced a cyber-attack which ended up costing between $50,000 to $99,999 - out of these companies, another 22% reported losing between $100,000 to $499,999.

Cybersecurity is a serious threat to every company across the world, which is why technological developments like microsegmentation are becoming so popular.

What Is Microsegmentation?

Although it is a relatively new concept, microsegmentation is already being utilised by companies worldwide to protect their cloud workload and provide security simplicity which wasn't achievable before.

Technically speaking, microsegmentation works by dividing a network into various parts - known as microsegments - to isolate every element of a network to reduce the attack surface. This allows architects to divide segments in tune with the individual workload level, meaning there are definitive security segments and protocols that work for each unique segment.

The reason this is utilised is because, rather than having a number of physical firewalls in your network, the security policies use network virtualisation technology to be entirely flexible and protect the data on an individual level.

How Does This Fight The Attacker?

By creating demilitarised "zones'', microsegmentation can install security across multiple data centres. This makes it far harder for an attacker to move laterally through a data centre, which subsequently holds off server-to-server threats. In essence, the attack surface of a network is reduced, and this ultimately reduces an attacker's playing field when it comes to breaching it.

Around the world, as much as 90% of organisations have at least one application on the cloud, with a further 42% using multi-cloud infrastructure. With over 2,200 cyberattacks happening every day, microsegmentation has become a viable and necessary solution to enable real-time visibility into suspicious activity and protect all workloads that exist on a multi-cloud infrastructure.

By escalating security across the segments, all resources become inaccessible to an attacker, which similarly halts data exfiltration and remedies an attempted attack almost instantly.

The Popularity Of Microsegmentation

So far, the top industries utilising microsegmentation include manufacturing - 95% - info and data services - 92% - and financial services - 92%. The market is growing, however, with a projected income of $3.61 billion between last year and 2026 and a compound annual growth rate of 28.04%.

Businesses worldwide, both big and small - cyberattacks on small companies rose by 150% between 2020 to 2021 -  are realising how important microsegmentation could be to protecting their network in the long run. Unlike many other cyber security protocols, microsegmentation doesn't just provide a padlock to the door of a network but, rather, several carefully crafted padlocks that are specific to each bolt.

This is not to mention the simplification of mandatory compliance regulations. Even with all protection protocols in place, it can be a difficult task for a business to ensure compliance when it comes to auditing, but microsegmentation defines the scope and allows for automated, auditable processes to be created and monitored, making the issue of compliance almost effortless.

The market is growing, and microsegmentation is proving to be a powerful tool in the fight against cyberattacks. As more and more companies get on board, so too will networks across the world become safer, simpler, and well-prepared to quell infiltration and keep businesses safe.
