When a virtual disk on a virtual machine is full, you need to increase the virtual disk size. However, partitions located on the virtual disk do not expand automatically and should be expanded manually. Learn how to increase the virtual disk size and extend Windows partitions using different methods and combine these methods for different scenarios. NAKIVO for VMware vSphere Backup Complete data protection for VMware vSphere VMs and instant recovery options.

Insufficient virtual disk space can lead to issues, including poor performance. For example, you set up a virtual disk, create partitions, and install a guest OS on one of those partitions. Then you find that you have insufficient disk space. In this case, you should extend the disk size. VMware provides flexible configuration options for virtual hardware like CPUs, memory, and disks, allowing you to extend the size of an existing virtual disk.

Each year, Identity Management Day (IMD) serves as a global reminder that managing digital identities is more than a technical requirement; it is a cornerstone of modern trust. Now in its sixth year, IMD continues to emphasize how identity itself is evolving, stretching beyond human users to encompass machines, automated agents, and even AI-generated personas.

DORA compliance isn’t optional for financial entities in the EU. The Digital Operational Resilience Act demands a systematic approach to identifying and closing ICT risk gaps, and the data shows most institutions are struggling. If you’re responsible for DORA compliance, you need a clear roadmap. Let us walk you through exactly how to conduct a gap assessment that actually works. Failure to meet DORA compliance requirements can lead to regulatory penalties and operational disruptions.

Every enterprise wants to use AI on its most valuable data — customer records, financial documents, clinical notes, legal files, engineering IP. The problem is simple: the moment that data enters an AI workflow, traditional security stops working. Firewalls protect the network. Encryption protects data at rest. Access controls protect the database. But none of them protect what happens when an AI agent retrieves five documents, synthesizes an answer, and delivers it to a user.

Mailcow is a widely used self-hosted and open source email server that hosts everything you'd need to manage mailboxes yourself. To assess its security, we set up a local instance and ran our AI pentesting agents against it. We found three XSS vulnerabilities, including a critical vulnerability that allowed unauthenticated attackers to take over administrator accounts while looking at their logs in the UI. Gaining access to a mailbox can have a serious security impact.

From AI agents to identity abuse, ATLSECCON 2026 focused on how security teams can reduce exposure, improve visibility, and make trust enforceable while moving ever faster.

The rise of AI-driven vulnerability discovery using Anthropic's Claude Mythos, as well as similar tools from Google and OpenAI, is completely changing the calculus of cyber risk. The number of vulnerabilities is exploding. The time it takes for exploits to appear is shrinking. The patching cadences and scan intervals, assessments and risk registers that many organizations still rely on are rapidly becoming ineffective.

NIST CSF 2.0 expands the Cybersecurity Framework into a broader, risk-based model centered on governance, making leadership accountable for cybersecurity as an enterprise risk. It introduces a sixth core function, enhances supply chain and privacy integration, and improves usability for organizations of all sizes. Profiles, tiers, and new implementation resources help align security efforts with business objectives and evolving threat landscapes.
