The Illusion of Internet Resilience

By / Blog / ,

2025 highlighted internet resilience failures; automation designed for reliability led to outages at AWS and Cloudflare. Centralized systems create vulnerabilities while complexity increases unforeseen interactions. The internet's architecture is flawed, necessitating new designs that prioritize safe automation and distributed defenses over mere scaling. We need real-time visibility into network operations to adapt and prevent future issues, especially with unpredictable AI workloads. True security involves rethinking our approach, acknowledging past mistakes, and moving away from “security theater.”

Ransomware Reshaping Cyber as National Security Priority

By / Blog / ,

Ransomware attacks in the US and UK have shifted the focus of cybersecurity from a technical issue to a matter of national security. High-profile incidents in both countries have caused significant disruptions and financial losses, prompting increased government scrutiny and calls for closer cooperation with the private sector. Policy proposals, such as banning ransom payments and disrupting crypto-enabled money flows, are under consideration, underscoring the need for both improved defenses and financial countermeasures.

The CISO’s Dilemma: Why Traceable, Branded AI Voice Is the Best Defense Against Deepfake Spoofing

By / Blog / ,

Deepfake voice fraud has escalated into a significant security issue, with attackers cloning executives' voices to commit fraud. Traditional voice verification is becoming less reliable, prompting organizations to adopt traceable, branded AI voice technology to ensure authenticity. This approach allows companies to treat voice identity similarly to secure documents, improving security by providing cryptographic verification and consistency. As voice-based threats grow, it’s vital for organizations to establish reliable methods of confirming legitimate voices to mitigate impersonation and fraud risks.

Passwords, MFA and AD Accounts: Hardening Your Environment for NIS2

By / Blog / , , ,

NIS2 mandates stricter cybersecurity for more sectors, emphasizing identity and access management (IAM). Key challenges include hardening Active Directory (AD) to secure authentication and authorization while ensuring compliance through robust password policies and multi-factor authentication (MFA). Organizations must adopt proactive measures, continuously monitor their systems, and maintain auditable identity processes. Failure to do so risks privilege escalation and network compromises. Recommendations for compliance include implementing fine-grained password policies, using passphrases, enforcing phishing-resistant MFA, and managing dormant accounts diligently. Ultimately, NIS2 provides a framework for organizations to enhance their cyber defenses and compliance efforts.

Fighting Payment Fraud With AI

By / Blog / , , , ,

AI combats payment fraud as criminals utilize it to execute attacks. Traditional defenses falter against AI-driven scams, leading to increased false declines of legitimate transactions. Static rule-based systems fail to adapt to evolving fraud tactics. AI enables real-time transaction analysis, enhancing accuracy and reducing losses by dynamically scoring risks. Companies like Stripe leverage AI for improved fraud prevention, leading to increased revenues and better customer experiences. Investing in AI for fraud prevention is now vital for growth and trust in e-commerce.

Criminal Networks Industrialize Payment Fraud Operations

By / Blog / , ,

Criminal networks are increasingly organized and industrialized in payment fraud, using tools like AI and botnets to automate attacks. A Visa report highlights a 477% rise in AI-related fraud tactics, with attacks evolving to exploit weaknesses and spread across multiple platforms. Monetization of stolen credentials has accelerated, often using rapid cash-out methods that evade detection. Synthetic content complicates identity verification, allowing fraudsters to masquerade as legitimate entities. Traditional fraud controls are becoming ineffective against these sophisticated and rapid tactics, increasing systemic risks through vulnerable third-party partnerships.
