Trying to achieve the pace, scale and time-to-market benefits that multicloud tech stacks present their new digital-first enterprise initiatives, making microsegmentation desk stakes is crucial for shielding future progress.

Gartner predicts that by means of 2023, at the least 99% of cloud safety failures would be the consumer’s fault. Getting microsegmentation proper in multicloud configurations could make or break any zero-trust initiative. Ninety p.c of enterprises migrating to the cloud are adopting zero belief, however simply 22% are assured their group will capitalize on its many advantages and remodel their enterprise. Zscaler’s The State of Zero Belief Transformation 2023 Report says safe cloud transformation is unattainable with legacy community safety infrastructure equivalent to firewalls and VPNs. 

Defining microsegmentation

Microsegmentation divides community environments into smaller segments and enforces granular safety insurance policies to attenuate lateral blast radius in case of a breach. Community microsegmentation goals to segregate and isolate outlined segments in an enterprise community, lowering the variety of assault surfaces to restrict lateral motion. 


It’s thought of one of many primary parts of zero belief and is outlined by NIST’s zero-trust framework. CISOs inform VentureBeat that microsegmentation is a problem in large-scale, complicated multicloud and hybrid cloud infrastructure configurations and so they see the potential for AI and machine studying (ML) to enhance their deployment and use considerably.

Gartner defines microsegmentation as “the flexibility to insert a safety coverage into the entry layer between any two workloads in the identical prolonged information middle. Microsegmentation applied sciences allow the definition of fine-grained community zones all the way down to particular person belongings and functions.”  

Microsegmentation is core to zero belief 

CISOs inform VentureBeat that the extra hybrid and multicloud the setting, the extra pressing — and complicated — microsegmentation turns into. Many CISOs schedule microsegmentation within the latter levels of their zero-trust initiatives after they’ve achieved a couple of fast zero belief wins. 

“You received’t actually be capable to credibly inform individuals that you simply did a zero belief journey in case you don’t do the micro-segmentation,” David Holmes, Forrester senior analyst mentioned in the course of the webinar “The time for microsegmentation is now,” hosted by PJ Kirner, CTO and cofounder of Illumio. 

Holmes continued: “I not too long ago was speaking to any person [and]…they mentioned, ‘The worldwide 2000 will at all times have a bodily community perpetually.’ And I used to be like, “You recognize what? They’re most likely proper.’ Sooner or later, you’re going to wish to microsegment that. In any other case, you’re not zero belief.”

CIOs and CISOs who’ve efficiently deployed microsegmentation advise their friends to develop their community safety architectures with zero belief first, concentrating on securing identities typically below siege, together with functions and information, as an alternative of the community perimeter. Gartner predicts that by 2026, 60% of enterprises working towards zero belief structure will use multiple deployment type of microsegmentation, up from lower than 5% in 2023. 

Each main microsegmentation supplier has energetic R&D, DevOps and potential acquisition methods underway to strengthen their AI and ML experience additional. Main suppliers embrace Akamai, Airgap Networks, AlgoSec, Amazon Net Providers, Cisco, ColorTokens, Elisity, Fortinet, Google, Illumio, Microsoft Azure, Onclave Networks, Palo Alto Networks, Tempered Networks, TrueFort, Tufin, VMware, Zero Networks and Zscaler.

Microsegmentation distributors provide a large spectrum of merchandise spanning network-based, hypervisor-based, and host-agent-based classes of options.

An efficient zero belief structure assumes the presence of hostile attackers within the community already, resulting in authenticating, encrypting, monitoring, and logging all interactions. Supply: Gartner, Information to Community Safety Ideas, 13 July 2023.

How AI and ML simplify and strengthen microsegmentation

Bringing better accuracy, pace and scale to microsegmentation is a perfect use case for AI, ML and the evolving space of latest generative AI apps based mostly on non-public Massive Language Fashions (LLMs). Microsegmention is commonly scheduled within the latter levels of a zero belief framework’s roadmap as a result of the large-scale implementation can typically take longer than anticipated. 

AI and ML may help enhance the chances of success earlier in a zero-trust initiative by automating probably the most handbook facets of implementation. Utilizing ML algorithms to find out how an implementation could be optimized additional strengthens outcomes by imposing the least privileged entry for each useful resource and securing each id.   

Forrester discovered that almost all of microsegmentation tasks fail as a result of on-premise non-public networks are among the many most difficult domains to safe. Most organizations’ non-public networks are additionally flat and defy granular coverage definitions to the extent that microsegmentation must safe their infrastructure absolutely. The flatter the non-public community, the more difficult it turns into to regulate the blast radius of malware, ransomware and open-source assaults together with Log4j, privileged entry credential abuse and all different types of cyberattack.

Startups leaping into the house

Startups see a possibility within the many challenges that microsegmentation presents. Airgap Networks, AppGate SDP, Avocado Methods and Byos are startups with differentiated approaches to fixing enterprises’ microsegmentation challenges. AirGap Networks is without doubt one of the high twenty zero belief startups to look at in 2023. Their strategy to agentless microsegmentation shrinks the assault floor of each linked endpoint on a community. Segmenting each endpoint throughout an enterprise whereas integrating the answer right into a working community with out machine adjustments, downtime or {hardware} upgrades is feasible.

Airgap Networks additionally launched its Zero Belief Firewall (ZTFW) with ThreatGPT, which makes use of graph databases and GPT-3 fashions to assist SecOps groups achieve new risk insights. The GPT-3 fashions analyze pure language queries and determine safety threats, whereas graph databases present contextual intelligence on endpoint visitors relationships.
