As 2025 wraps up, three topics dominated reader interest on the Edgescan blog. Not because they were trendy, but because they addressed real problems security teams face every day.
Here’s what resonated most – and why these challenges won’t disappear in 2026.
Continuous Threat Exposure Management: From Buzzword to Foundation
CTEM became impossible to ignore in 2025. Gartner’s research quantified what many already suspected: organisations prioritising security investments through CTEM programmes will realise a two-thirds reduction in breaches by 2026.
But CTEM isn’t new for everyone. At Edgescan, we’ve been building continuous assessment, validation, and prioritisation into our platform for years – long before analysts formalised the framework.
The model is straightforward: discover your attack surface, assess vulnerabilities continuously, validate findings to eliminate false positives, prioritise based on actual risk, and remediate systematically. Then repeat. Traditional quarterly penetration tests and periodic scans can’t keep pace with modern attack surfaces that change daily through cloud deployments, API updates, and infrastructure shifts.
According to Edgescan’s 2025 Vulnerability Statistics Report, organisations average 74.3 days to remediate critical application vulnerabilities, while 45.4% of enterprise vulnerabilities remain unpatched after 12 months. Point-in-time testing doesn’t solve this – continuous exposure management does.
The lesson: Security must operate continuously, not occasionally. CTEM provides the framework, but only platforms built for continuous operation can deliver on it.
Cloud-Native Security: Meeting Teams Where They Work
Edgescan’s launch on AWS Marketplace generated significant interest for a simple reason: it removes friction. Security teams working in cloud-native environments need tools that integrate naturally with their workflows, procurement processes, and existing infrastructure.
Making Edgescan available through AWS Marketplace means organisations can streamline procurement, leverage AWS spend commitments, and integrate penetration testing and vulnerability management directly into cloud operations. No separate vendor relationships. No complex procurement cycles. Just security that works where your assets actually live.
This matters because cloud adoption isn’t slowing down. Neither are the security challenges that come with it. According to our vulnerability data, 32.2% of network and infrastructure vulnerabilities are critical or high severity, compared to 14.8% for applications and APIs. Cloud environments blend these layers constantly, creating attack chains that span multiple technology stacks.
Security solutions that don’t integrate with cloud platforms create organisational friction at exactly the wrong time – when speed and visibility matter most.
The lesson: Security tools must integrate with the environments teams already use. Anything else just adds overhead without adding protection.
The Invisible Attack Surface: Bluetooth and Beyond
One of our most-read posts examined something most security programs ignore: Bluetooth. The response proved that security teams recognise threats extend beyond traditional perimeters.
Bluetooth isn’t inherently dangerous – it’s just universally deployed, often enabled by default, and rarely included in security assessments. Devices broadcast identifiers constantly. Older implementations don’t rotate MAC addresses. And in BYOD environments, these personal devices connect to corporate networks without rigorous security validation.
The Bluetooth discussion highlighted a broader challenge: IoT devices, wearables, smart building systems, and other “assumed-safe” technology create attack surfaces that traditional vulnerability management doesn’t cover. These aren’t hypothetical risks – they’re exploitation paths attackers already use.
As connected devices proliferate in enterprise environments, the gap between “assets we assess” and “assets that exist” widens. Security programs need visibility into the entire technology ecosystem, not just the parts that fit neatly into traditional scanning tools.
The lesson: Modern attack surfaces include everything connected to your network, not just the systems you intentionally deployed.
Three Themes for 2026
Looking at what resonated in 2025, three priorities emerge for the year ahead:
Continuous Operation: One-off assessments can’t keep pace with continuous change. Security programs need platforms built for ongoing discovery, validation, and prioritisation – not just annual penetration tests.
Integration Over Addition: Security tools that don’t integrate with existing workflows create friction and slow response times. Cloud-native security isn’t optional anymore; it’s table stakes.
Expanding Visibility: Attack surfaces now include APIs, IoT devices, cloud workloads, and forgotten infrastructure. Effective security requires visibility across all of it, not just the obvious targets.
These aren’t predictions – they’re observations from working with hundreds of organisations managing real security programs. The challenges exist today. They’ll intensify in 2026.
At Edgescan, we’re focused on the same things we’ve always prioritised: validated vulnerability intelligence, full-stack coverage, continuous assessment, and platforms that integrate with how organisations actually work. Not because it’s trendy, but because it’s what effective security requires.
