The 2025 Cisco Segmentation Reportwith 1,000 respondents, was launched final month and has prompted me to assume extra deeply in regards to the evolution of the decades-old cybersecurity idea and the way it continues to adapt to fulfill the wants of recent enterprises. I beforehand wrote that whereas 79% of respondents contemplate 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 very best for implementing a proactive method to enterprise cybersecurity right this moment. 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 primarily based on habits or id. This twin segmentation method is well-suited to guard right this moment’s distributed, cloud-first community infrastructure and the functions, knowledge, 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 in regards to the present state of segmentation.
Macro-Segmentation (On It’s Personal) Is Not Sufficient to Meet At this time’s Cybersecurity Challenges
Macro-segmentation alone is inadequate as a result of latest modifications in fashionable software structure. Trendy functions are not monolithic, and they’re not constrained by a subnet or VLAN. In consequence, these functions are decentralized and composed of a number of workloads. This new decentralized structure has boosted software efficiency, scalability, maintainability, and reliability; nevertheless, it has made it difficult to grasp what’s taking place on the workload stage.
Nonetheless, the shortage of visibility and management on the workload stage makes conventional safety approaches (together with macro-segmentation) difficult. It’s no marvel that cybersecurity groups are struggling to guard right this moment’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 permits safety groups to separate IT environments into sections whereas isolating particular person workloads primarily based on their habits or id. This allows a proactive method 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 median 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 median of 29 days.
It is a massive, massive deal. Chopping restoration time by one-third limits the breach’s impression and prevents its future unfold. Simply think about the injury that risk actors can inflict in these further 9 days. The mixture of macro- and micro-segmentation slows down attackers. It additionally gives defenders with extra visibility and management over particular person workloads, providing insights into the assault chain that allow them to shortly determine which belongings should be quarantined, taken offline, and recovered.
2. An Alternative to Align Groups
Segmentation tasks 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 workforce is aware of who created an software, however it might not have visibility into who’s utilizing the appliance or how the appliance is getting used. A failure to coordinate throughout groups can result in over-permissioning—a standard mistake that creates vital dangers for organizations.
In response to the survey, organizations (typically) 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 remove a lot of the danger related to over-permissioning. Persevering with with our growth workforce instance, the drive towards segmentation can deliver the event workforce nearer to these managing and securing the community by establishing a standard 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 response to the report, two-thirds (63%) of respondents at organizations with full implementation strongly agree that automation is essential to scaling and maturing segmentation tasks, versus 50% with out full implementation of each. Automation permits organizations to scale their segmentation insurance policies throughout the complete group (or not less than the place it is sensible), leading to extra complete and constant enforcement, and finally, stronger safety controls. Organizations that don’t make use of satisfactory automation should manually create and preserve insurance policies, which might simply fall behind safety necessities over time.
A Twin Strategy Allows a Proactive Cybersecurity Technique
The flexibility to implement micro-segmentation at scale together with macro-segmentation has grow to be foundational to fashionable enterprise safety methods and the zero-trust safety mannequin. This allows organizations to get better extra shortly, higher align their groups, and implement segmentation extra persistently—together, permitting for a proactive method to cybersecurity. Though segmentation is an outdated idea (from an IT perspective, in fact), it stays a important element of a proactive enterprise safety method—primarily as a result of its adaptation for contemporary environments.
In my subsequent weblog, I’ll define the challenges organizations are going through right this moment when implementing segmentation tasks. Within the meantime, obtain the 2025 Cisco Segmentation Report to higher perceive the state of segmentation right this moment.
