The Surprising Role of Patching in Cybersecurity

A surprising finding in the report is that patching scored the lowest in terms of perceived importance. However, patching remains one of the most effective ways to prevent cyberattacks. This discrepancy likely stems from the difficulties of implementing patches in distributed environments.

Here’s why patching can be challenging, and critical:

Open Source Software Risks: Many companies rely on open-source software, which can contain hidden vulnerabilities. Patching these vulnerabilities is essential but requires consistent monitoring and response.
Zero-Day Threats: Patching is not always possible for zero-day vulnerabilities, making proactive threat detection even more crucial in environments with open-source software dependencies.
Organizational Priorities: AT&T recommends that organizations develop a structured vulnerability notification process to stay informed and responsive to patch needs.

For organizations facing challenges with patching, tools like Keepnet Threat Intelligence can enhance threat visibility and help identify vulnerabilities before attackers exploit them.

Adopting a Shared Responsibility Model

In today’s decentralized environments, security isn’t solely an IT responsibility. AT&T’s report emphasizes a shared responsibility model, which requires collaboration across departments and teams to protect the network. This model is particularly vital as more devices, sensors, and data points connect to distributed networks.

Key benefits of a shared responsibility model include:

Enhanced Communication and Awareness: When all team members understand the role they play in maintaining security, response times improve, and potential vulnerabilities can be addressed more swiftly.
Informed Decision-Making: Cross-departmental collaboration enables more informed decisions, which are crucial for implementing effective security strategies.
Cost Efficiency: Collaborative threat intelligence efforts, such as Threat Sharing, empower organizations to cut down on expenses while gaining timely insights on potential threats.

One of the report’s standout recommendations is the need for collective threat intelligence, which aligns closely with the Keepnet Threat Sharing tool. By sharing intelligence across organizations, industries can stay updated on emerging threats, minimize risks, and reduce response times.

Threat Sharing enables enterprises to leverage shared network expertise, equipping them to:

Gain Early Insights: Collective intelligence allows organizations to anticipate potential attacks, providing an early warning system.
Reduce Costs: By pooling resources, organizations can cut down on the expenses related to threat detection and monitoring.
Accelerate Security Deployments: Threat sharing accelerates the process of deploying security measures, reducing the time between threat identification and mitigation.

Frequently Asked Questions

What is AT&T's Cybersecurity Insights Report?

AT&T's Cybersecurity Insights Report is an annual research publication that surveys security practitioners, IT leaders, and business executives worldwide to identify the most pressing cybersecurity trends, threats, and recommendations. The 11th edition focused specifically on edge computing security — exploring how the shift from centralized to decentralized network architectures is reshaping the threat landscape. The report provides data-driven guidance on topics including ransomware defense, Zero Trust adoption, patching strategies, and the shared responsibility model. It is one of the most widely cited industry reports for organizations planning their cybersecurity strategies.

What is edge computing and why does it create new security challenges?

Edge computing is a distributed architecture that processes data closer to its source — at IoT devices, sensors, gateways, or local servers — rather than sending it to centralized cloud data centers. This reduces latency and enables real-time applications, but dramatically increases the attack surface. By 2026, over 32 billion IoT devices are connected globally (Statista), and 75% of enterprise data is processed outside centralized data centers. Each edge device represents a potential entry point for attackers. Unlike cloud environments, edge devices often have limited memory, inconsistent firmware updates, and minimal built-in security controls — making them attractive targets for lateral movement and ransomware deployment.

What is Zero Trust security and why does AT&T recommend it for edge environments?

Zero Trust is a security framework built on the principle that no user, device, or application should be automatically trusted — regardless of whether it is inside or outside the network perimeter. Every access request must be continuously verified before being granted. AT&T's report recommends Zero Trust as a foundational approach for edge environments because the traditional perimeter-based security model fails when data and computation are distributed across thousands of endpoints. In 2026, Zero Trust adoption continues to accelerate, driven by regulatory requirements (NIST SP 800-207), the proliferation of remote work, and the growth of cloud-native and edge-native architectures.

Why does the AT&T report highlight patching as undervalued?

One of the report's most striking findings was that patching scored the lowest in perceived importance among respondents — despite being one of the most effective defenses against cyberattacks. The reason is largely practical: in distributed edge environments, applying patches to thousands of heterogeneous devices with varying firmware, protocols, and update cadences is operationally complex. Yet the consequences of delaying patches are severe — unpatched vulnerabilities accounted for 32% of ransomware attacks in 2025 (Sophos). AT&T recommends organizations develop a structured vulnerability notification process and automate patch management wherever possible, especially for open-source software dependencies.

What is Security as a Service (SaaS/SAS) and how does it help edge security?

Security as a Service (SaaS or SAS) refers to delivering cybersecurity capabilities — such as threat detection, identity management, SIEM, and endpoint protection — through cloud-based subscription models rather than on-premises hardware. AT&T's report recommends SAS as a key component of edge security because it enables organizations to extend consistent security policies across distributed environments without requiring dedicated security hardware at each edge location. In 2026, SaaS-based security platforms — including cloud-delivered SASE (Secure Access Service Edge) frameworks — are increasingly the standard for organizations managing hybrid and edge network architectures.

What is threat intelligence sharing and why is it important?

Threat intelligence sharing is the practice of organizations exchanging real-time information about emerging cyber threats, attack indicators, vulnerabilities, and attacker tactics with peers, government agencies, or industry-specific information sharing groups (ISACs). AT&T's report identifies this as a standout recommendation because no single organization can monitor the entire threat landscape alone. Collective intelligence enables earlier detection of novel attack campaigns, reduces response times, and distributes the cost of threat research. In 2026, automated threat sharing platforms — integrated with SIEM and SOAR tools — allow organizations to act on shared intelligence within seconds of a threat being identified elsewhere.

How does AI impact edge computing security in 2026?

AI is transforming edge security in two opposing ways. On the attacker side, threat actors now use AI to automate vulnerability discovery across distributed edge endpoints, generate convincing deepfake phishing lures targeting edge network administrators, and deploy adaptive malware that evades signature-based detection. Ransomware operators increasingly use AI to accelerate reconnaissance and payload deployment across distributed edge systems. On the defensive side, AI-powered tools enable anomaly detection across massive volumes of edge telemetry data in real time, automate threat response, and reduce mean time to detection (MTTD) significantly — critical in environments where manual monitoring of thousands of edge devices is impractical.

What is the shared responsibility model in cybersecurity?

The shared responsibility model is a framework that distributes cybersecurity ownership across multiple stakeholders rather than treating it as an exclusively IT function. AT&T's report emphasizes this model as essential for edge environments because the distributed nature of edge computing means that operational technology (OT) teams, business units, and even supply chain partners all manage devices that connect to the network. In practice, this means: IT teams own network-level security policies; business units own compliance with security procedures for their devices and data; and leadership owns the risk appetite and investment decisions. Human error accounts for 95% of security incidents (IBM) — making employee awareness and clear accountability essential.

How can security awareness training help organizations secure edge environments?

The shift to edge computing makes human risk management more critical, not less. As more employees interact with edge devices — from factory floor workers scanning IoT sensors to remote employees using cloud-connected devices — the human attack surface expands. Phishing remains the primary initial access vector for ransomware and other edge-targeting threats. Organizations that run regular security awareness training, including phishing simulations, social engineering exercises, and role-specific training tailored to OT and IoT environments, build a workforce that is the first line of detection rather than the first point of failure. Keepnet's Security Awareness Training platform offers 2,000+ modules across 30+ languages and behavior-based simulations that adapt to each employee's risk profile.

What are the most important steps for organizations to act on from AT&T's edge security report in 2026?

Building on AT&T's recommendations and 2025-2026 threat intelligence, the most impactful actions organizations should take are: (1) Adopt a Zero Trust architecture — assume breach and verify every access request, especially from edge and IoT devices; (2) Automate patch management — prioritize vulnerability remediation for edge devices, particularly open-source components; (3) Deploy real-time threat intelligence — use tools like Keepnet Threat Intelligence to monitor for breached credentials and emerging attack patterns targeting edge infrastructure; (4) Implement phishing-resistant MFA — passkeys and FIDO2 keys protect edge administrator accounts from credential theft; (5) Conduct regular phishing simulations — employees managing edge systems need realistic training on social engineering tactics; (6) Build and test an incident response plan — organizations with tested IR plans contain breaches 58 days faster on average; and (7) Join a threat sharing community — collective intelligence dramatically accelerates detection of novel edge attack campaigns.
