Recent reports published by Integrity360’s partners at CrowdStrike and Fortinet points to a threat landscape increasingly defined by speed, automation, AI-enabled activity, identity abuse, cloud exploitation and attackers moving across endpoints, networks, SaaS applications and cloud infrastructure.

One standout stat from the reports is that 87% of intrusions involve activity across multiple attack surfaces. This raises the question; is Managed Detection and Response (MDR) the best tool to prevent them?

Why single-point security is no longer enough

Attackers no longer rely on a single compromised endpoint or obvious malware payload to succeed. Intrusions often begin with stolen credentials, exposed internet-facing systems, vulnerable cloud workloads, misconfigured SaaS applications or trusted third-party access. From there, adversaries move laterally, abuse legitimate tools and blend into normal business activity.

The 2026 CrowdStrike Global Threat Report highlights how quickly this shift is happening. It found that AI-enabled adversary attacks increased by 89% year on year, while the average eCrime breakout time fell to just 29 minutes. The fastest observed breakout took only 27 seconds, and in one case data exfiltration began within four minutes of initial access. The same report also found that 82% of detections were malware-free, showing how attackers increasingly exploit valid credentials, trusted identity flows, SaaS integrations and legitimate systems rather than relying on traditional malware.

This matters because many traditional security models were built around perimeter defence, endpoint protection or malware detection. Those controls remain important, but they cannot address the full reality of multi-surface intrusion on their own. If an attacker moves from identity to SaaS, from SaaS to cloud, from cloud to unmanaged devices and then into the wider network, a fragmented set of tools may not provide enough correlation, context or speed.

That is where MDR becomes essential.

What MDR does well

MDR gives organisations the ability to monitor, detect, investigate and respond to threats around the clock. A mature MDR service does not simply generate alerts. It brings together telemetry, threat intelligence, human expertise and response processes to identify suspicious behaviour across multiple areas of the environment.

In the context of multi-surface intrusions, MDR is valuable because it can help connect activity that might otherwise appear isolated. A suspicious login, unusual SaaS behaviour, anomalous endpoint activity and unexpected cloud access may not trigger a decisive response when viewed separately. When correlated together, they may indicate an active intrusion.

This is why MDR is especially important in an era of malware-free activity. If attackers are abusing legitimate accounts and trusted systems, defenders need behavioural detection, identity monitoring, cloud visibility, threat hunting and experienced analysts capable of identifying what should not be happening.

The CrowdStrike report also notes that cloud-conscious intrusions rose by 37% in 2025, including a 266% increase among state-nexus threat actors. Valid account abuse accounted for 35% of cloud incidents, reinforcing that identity has become central to intrusion.

That makes MDR critical for threat response and containment, but it still does not remove the need for proactive risk reduction.

Why MDR alone is not enough

MDR helps detect and respond to suspicious or malicious activity, but it cannot, by itself, remove every exposure that gives attackers an opening. If an organisation has unpatched internet-facing systems, weak access controls, unmanaged assets, excessive privileges, insecure cloud configurations or exposed credentials, MDR may help detect the resulting attack, but the initial opportunity still exists.

The Fortinet 2026 Global Threat Landscape Report shows the scale of this challenge. Fortinet telemetry recorded 640 billion reconnaissance events, 67.65 billion brute-force attempts and 121.99 billion exploitation attempts globally in 2025. Exploitation attempts were up 25% year on year. The report also found that of 635 vulnerabilities observed under active exploitation, 53.86% had publicly available proof-of-concept code and 31.18% had fully functional exploit code. Time-to-exploit was consistently observed within 24 to 48 hours, outpacing traditional patch and remediation timelines.

Attackers are constantly scanning, validating and exploiting exposures at scale. If defenders do not continuously understand and prioritise their own risk, they will always be reacting late.

The role of threat exposure management

Threat exposure management helps organisations understand how exposed they are from an attacker’s perspective. Rather than treating every issue equally, it helps identify the vulnerabilities, misconfigurations, attack paths and weaknesses that create the greatest real-world risk.

This is particularly important when security teams are overwhelmed by long lists of findings. Not every exposure represents the same level of business risk. Some issues may be technically serious but difficult to exploit. Others may appear minor in isolation but become dangerous because of where they sit in the environment or how they connect to critical systems.

Threat exposure management helps security teams answer more useful questions such as:

• Which assets are exposed to the internet?
• Which identities have excessive privileges?
• Which cloud misconfigurations could enable lateral movement?
• Which known exposures are actively being exploited?
• Which attack paths could lead to critical business systems?

In short, organisations need to reduce exposure before attackers, increasingly supported by AI and automation, can exploit it.

Why MDR and threat exposure management work better together

The strongest defence against multi-surface intrusions is not MDR or threat exposure management in isolation. It is both working together. Read our blog on this topic HERE

Threat exposure management reduces the chance of compromise by helping organisations identify and prioritise the exposures that matter most. MDR reduces the impact of compromise by detecting suspicious activity, investigating incidents and enabling rapid containment.

Exposure management may identify an externally facing system with a known exploitable weakness, a cloud identity with excessive permissions or a SaaS configuration that increases the risk of data exposure. Remediating those issues reduces the opportunity for attack. If an attacker still attempts to exploit a related pathway, MDR provides the monitoring, investigation and response capability needed to identify the behaviour quickly and act before the intrusion escalates. This is especially important when attackers are moving faster than traditional security processes. With breakout times measured in minutes, and exploitation occurring within 24 to 48 hours of disclosure in many cases, organisations need both continuous exposure reduction and 24/7 detection and response.

The AI factor: faster attackers, wider attack surfaces

AI is not creating an entirely new threat landscape from scratch, but it is accelerating the one organisations already face.

This should concern any organisation still relying on periodic assessments, manual patch prioritisation or disconnected security tools. Attackers are using automation to find and exploit opportunities faster. Security teams need a model that can keep pace.

This is where Integrity360’s approach is especially relevant. Organisations need visibility across endpoints, networks, cloud, SaaS and identity. They need continuous exposure management to understand where they are vulnerable. They need MDR to identify and respond to active threats. They also need expertise to tune, optimise and mature their security operations over time.

How Integrity360 can help

Integrity360 helps organisations defend against modern multi-surface intrusions by combining proactive exposure reduction with managed detection and response.

Through Integrity360’s Threat Exposure Management services, organisations can gain a clearer view of their attack surface, identify exploitable exposures, prioritise remediation based on real-world risk and continuously improve their security posture. This is essential for reducing the opportunities attackers rely on.

Through Integrity360’s Managed Detection and Response services, organisations can strengthen 24/7 monitoring, threat detection, investigation and response across complex environments. MDR helps organisations identify suspicious activity earlier, respond faster and contain incidents before they become business-disrupting events.

Integrity360 can also support broader resilience through services including cybersecurity testing, cloud security, incident response, threat intelligence, identity security and advisory support. This matters because multi-surface intrusions require more than one control, one tool or one team. They require joined-up security built around visibility, context and speed.

Threat exposure management helps reduce the attack paths available to adversaries. MDR helps detect and contain the adversary when activity begins. Together, they give organisations a more complete way to defend endpoints, networks, cloud infrastructure, SaaS applications and identity.

Integrity360 can help you understand where you are exposed, improve your ability to detect and respond, and build a cybersecurity programme capable of keeping pace with modern attackers.
