The 2025 Cisco Segmentation Reportwith 1,000 respondents, was launched final month and has prompted me to suppose extra deeply concerning the evolution of the decades-old cybersecurity idea and the way it continues to adapt to fulfill the wants of contemporary enterprises. I beforehand wrote that whereas 79% of respondents think about segmentation a high precedence, solely 33% implement it absolutely. The survey outcomes additionally revealed fascinating insights into why segmentation stays a foundational idea.
The evolution of segmentation and the event of various segmentation approaches make the idea splendid for implementing a proactive strategy to enterprise cybersecurity at this time. For years, organizations have utilized macro-segmentation to divide networks into smaller sections, which helps restrict the unfold of profitable assaults whereas enhancing general resilience. And now, augmenting macro-segmentation with micro-segmentation implementations permits safety groups to separate environments into separate networks AND isolate particular workloads based mostly on habits or identification. This twin segmentation strategy is well-suited to guard at this time’s distributed, cloud-first community infrastructure and the functions, information, and customers that depend on these important networks.
That is the primary a part of a three-part collection that delves deeper into the survey outcomes and what they reveal concerning the present state of segmentation.
Macro-Segmentation (On It’s Personal) Is Not Sufficient to Meet Right now’s Cybersecurity Challenges
Macro-segmentation alone is inadequate on account of current adjustments in fashionable utility structure. Trendy functions are not monolithic, and they’re not constrained by a subnet or VLAN. Because of this, these functions are decentralized and composed of a number of workloads. This new decentralized structure has boosted utility efficiency, scalability, maintainability, and reliability; nevertheless, it has made it difficult to grasp what’s taking place on the workload degree.
Nonetheless, the shortage of visibility and management on the workload degree makes conventional safety approaches (together with macro-segmentation) difficult. It’s no marvel that cybersecurity groups are struggling to guard at this time’s extremely distributed, cloud-first digital infrastructures.
Organizations Have to Implement Macro-Segmentation and Micro-Segmentation in Tandem
Augmenting macro-segmentation with micro-segmentation implementations allows safety groups to separate IT environments into sections whereas isolating particular person workloads based mostly on their habits or identification. This allows a proactive strategy to cybersecurity, leading to sooner restoration occasions, improved operations, and constant enforcement of segmentation insurance policies.
1. Faster Restoration Instances
Respondents from organizations which have absolutely carried out each macro- and micro-segmentation report that breach containment and restoration take a mean of 20 days to finish. In distinction, respondents from organizations that haven’t absolutely carried out each macro- and micro-segmentation report that restoration takes them a mean of 29 days.
This can be a massive, massive deal. Slicing restoration time by one-third limits the breach’s influence and prevents its future unfold. Simply think about the injury that risk actors can inflict in these extra 9 days. The mix of macro- and micro-segmentation slows down attackers. It additionally supplies defenders with extra visibility and management over particular person workloads, providing insights into the assault chain that allow them to rapidly determine which belongings should be quarantined, taken offline, and recovered.
2. An Alternative to Align Groups
Segmentation initiatives require coordination throughout a number of groups with a number of layers of duty, necessitating full alignment all through the group. For instance, a growth crew is aware of who created an utility, however it might not have visibility into who’s utilizing the applying or how the applying is getting used. A failure to coordinate throughout groups can result in over-permissioning—a typical mistake that creates vital dangers for organizations.
In accordance with the survey, organizations (usually) depend on three separate groups for implementing and managing segmentation—IT infrastructure or community (87%), Safety/ SecOps (77%), and DevOps/ Cloud Engineering (71%). The method of implementing each macro- and micro-segmentation can enhance alignment between these groups and get rid of a lot of the danger related to over-permissioning. Persevering with with our growth crew instance, the drive towards segmentation can carry the event crew nearer to these managing and securing the community by establishing a typical vocabulary and shared goals.
Amongst survey respondents at organizations which have absolutely carried out each macro- and micro-segmentation, 87% report that their groups are absolutely aligned, in contrast with 52% of these at organizations with out full implementation.
3. Constant Enforcement
In accordance with the report, two-thirds (63%) of respondents at organizations with full implementation strongly agree that automation is vital to scaling and maturing segmentation initiatives, versus 50% with out full implementation of each. Automation allows organizations to scale their segmentation insurance policies throughout your complete group (or at the very least the place it is smart), leading to extra complete and constant enforcement, and finally, stronger safety controls. Organizations that don’t make use of enough automation should manually create and preserve insurance policies, which may simply fall behind safety necessities over time.
A Twin Strategy Allows a Proactive Cybersecurity Technique
The flexibility to implement micro-segmentation at scale along with macro-segmentation has change into foundational to fashionable enterprise safety methods and the zero-trust safety mannequin. This allows organizations to recuperate extra rapidly, higher align their groups, and implement segmentation extra constantly—together, permitting for a proactive strategy to cybersecurity. Though segmentation is an previous idea (from an IT perspective, after all), it stays a important element of a proactive enterprise safety strategy—primarily on account of its adaptation for contemporary environments.
In my subsequent weblog, I’ll define the challenges organizations are dealing with at this time when implementing segmentation initiatives. Within the meantime, obtain the 2025 Cisco Segmentation Report to raised perceive the state of segmentation at this time.
