AI Tool Poisoning: How Hidden Instructions Threaten AI Agents

As AI agents become increasingly prevalent across business environments, their security is a pressing concern. Among the insidious threats facing AI agents is tool poisoning, a type of attack that exploits the way AI agents interpret and use tool descriptions to guide their reasoning. In this blog, we explain how AI tool poisoning works, the different forms it can take, and how organizations can strengthen their defenses against this type of attack.

CVE-2026-21858: Critical Unauthenticated File Access Vulnerability in n8n "Ni8mare"

On January 7, 2026, fixes were released for a maximum severity vulnerability (CVE-2026-21858) impacting n8n, a workflow automation application primarily used with artificial intelligence. Labeled “Ni8mare” by the researchers who discovered it, the vulnerability allows unauthenticated remote threat actors to take over locally deployed instances via publicly accessible webhook and form endpoints.

Enterprise PCI Compliance: The Cost of Getting It Right in 2026

PCI used to fit neatly into a budget. You’d build your cardholder data environment, lock it down, gather evidence, and once a year prove to an assessor that everything worked. Costs were predictable because the work was concentrated: audit cycle, remediation sprint, then relative quiet until next year. That model broke somewhere around 2018. Now your payment flow touches cloud accounts, shared services, SaaS vendors, front-end code, and operational teams deploying changes on their own schedules.

Backup strategies for operational technology (OT) systems

Summary Operational technology (OT) systems underpin industrial safety and production, yet many run on legacy platforms that lack modern backup and cyber-resilience. Without isolated, full-system recovery, ransomware or system failure can halt operations and create serious safety risks — a gap addressed by modern OT backup approaches such as Acronis Cyber Protect.

Workspace security in 2026: A complete guide for MSPs and modern IT teams

Workspace security has evolved into one of the most critical challenges facing managed service providers and modern IT teams. As organizations continue to embrace remote and hybrid work models, traditional perimeter-based security approaches no longer provide adequate protection. Users now access corporate data from multiple locations, devices and cloud platforms, dramatically expanding the attack surface. For MSPs, this shift represents both a risk and an opportunity.

CMMC Incident Response Timelines and Reporting Rules

Information security frameworks like CMMC are not just about enforcing security. They’re about enforcing accountability. That’s why a whole section of controls and rules that make up CMMC centers around incident response and reporting. You can’t just have security in place, but throw your hands up and do nothing if there’s an incident or breach. Nor can you sweep it under the rug and hope no one notices.

How to easily protect your identity from theft and fraud

Identity theft is no longer just about lost wallets or stolen credit cards—it’s a growing digital threat that can start with something as simple as opening an email, clicking a link, or sharing information online. Criminals can use your personal data to open accounts, make purchases, or commit fraud in your name, and may also use your information to commit crimes beyond financial fraud, often leaving victims unaware until serious financial or legal damage occurs.

Identity Assurance: Reinventing Trust in a Cyber-First World

Identity is everything. Hamper it, and the individual is left with disrupted privacy, reputation damage, and endless fraud. Attackers are always on the lookout for access to resources and accounts via identity theft, credential theft, and Account Takeover Attacks (ATO). So, it is paramount to leverage solutions that securely link a user’s identity with who they claim to be. Identity assurance offers frameworks, components, and best practices to safeguard modern-day identities.

5 Best Global HR and Payroll Platforms With Strong Data Protection Standards

Running global HR and payroll means handling personal data at a massive scale. Bank account numbers, tax identifiers, salary information, performance reviews, and employment records flow through these systems constantly. A security lapse doesn't just create operational problems. It triggers regulatory penalties, erodes employee trust, and exposes the organization to legal risk across multiple jurisdictions.

Supply Chain Security-4 Weak Spots Worth Fixing Now, Not Later

Supply chains are marvels of coordination, but they are also deeply human creations, which means assumptions sneak in, shortcuts feel sensible, and comfort zones harden over time. The smartest organizations are not the most paranoid ones. They are the most curious. They ask where things might wobble, not because they expect disaster, but because they respect complexity. The four vulnerabilities below are common, understandable, and manageable, which is precisely why they deserve attention now, while choices are still choices and not apologies.
