A cyberattack can last just a few hours, but its financial consequences can affect a business for months or even years. Lost revenue, operational downtime, incident response, legal expenses, regulatory penalties, and reputational damage can turn a single security incident into a major financial problem.

ChatGPT and other generative AI tools have quickly become part of everyday business operations. Employees use them to write content, analyze documents, review code, summarize reports, translate information, conduct research, and automate routine tasks.

Preparing for a SOC 2 audit? Small gaps in access management, audit evidence, security policies, vendor risk, or incident response can become problems once audit testing begins. Here are seven common SOC 2 readiness issues to identify and fix before your auditor finds them.

Not every company needs a full-time CISO, but every company needs security ownership. Here are seven cybersecurity decisions that cannot be left without a clear owner — from risk acceptance and access control to incident response and compliance.

Cybersecurity risks are not always caused by technical vulnerabilities. Unclear security ownership, excessive access, weak offboarding, third-party access, and untested processes can create serious attack paths. Learn which non-technical security gaps companies often overlook and how to identify them before attackers do.

Shadow AI is becoming a growing cybersecurity risk as employees use ChatGPT, AI assistants, coding tools, and other AI services without IT oversight. Learn how Shadow AI can expose corporate data, source code, customer information, and personal data and how organizations can reduce the risk with DLP, CASB, Data Access Governance, AI policies, and security awareness.

Cybersecurity due diligence helps buyers uncover hidden cyber risks before an M&A deal closes. Learn what to assess, from vulnerabilities, cloud security, and privileged access to data breaches, compliance, and existing compromise and how these risks can affect valuation, deal terms, and post-merger integration.

Corporate credentials, passwords, VPN access, and active sessions can appear on the Dark Web long before a company detects an attack. Learn how business data gets exposed, how Dark Web Monitoring and Threat Intelligence help identify compromised information, and what to do if your company’s data is found.

Business Email Compromise (BEC) attacks use executive impersonation, compromised email accounts, and social engineering to trick employees into transferring money or revealing sensitive data. Learn how BEC works, why SPF, DKIM, and DMARC are not enough, and how to protect your company from email-based financial fraud.

What really happens during a penetration test? Explore the full pentesting process, from scoping and reconnaissance to vulnerability exploitation, reporting, remediation, and retesting and learn what your company should expect at every stage.

Despite significant investments in cybersecurity technologies, phishing remains one of the most successful attack vectors used by cybercriminals. Firewalls, endpoint protection, email filtering, and advanced detection systems are essential layers of defense, but they cannot completely eliminate the human factor. Attackers understand this well, which is why they continue to target employees rather than systems.

Many companies invest heavily in protecting their own infrastructure. They deploy firewalls, endpoint protection, multi-factor authentication, backup systems, and security monitoring. Internal systems become increasingly difficult to compromise. So attackers change their strategy. Instead of attacking the organization directly, they target someone the organization already trusts. A software vendor. A cloud service provider. An IT outsourcing company. A managed service provide

One conversation plays out in almost every company when it's time to discuss the cybersecurity budget. The CISO or IT Director walks into a meeting with a list of security initiatives, software, and services the organization needs. The CEO or CFO looks at the numbers and asks: "Why do we need all of this? Nothing has happened to us." The security team starts talking about threats, vulnerabilities, and attack vectors. Management hears technical terminology but struggles to con

When a company begins thinking seriously about cybersecurity, one question usually comes up: “Fine, we bring in a vCISO. But what exactly will change in the way the business operates?” Most descriptions of the role sound too abstract. They talk about strategy, risk management, governance, and security process development. These concepts are important, but business leaders usually want something more practical: specific actions, visible progress, and measurable outcomes. That

When a security incident occurs, the first instinct in most organizations is to restore operations as quickly as possible. Rebuild the affected systems, reset credentials, patch the vulnerability, and move on. It is an understandable response, downtime is expensive and pressure from leadership is immediate. It is also one of the most damaging decisions a security team can make. Restoring systems before conducting a forensic investigation destroys evidence. Without that eviden

A few years ago, security questionnaires were something large enterprises sent to enterprise vendors. Today, they land in the inboxes of mid-sized companies, startups, and regional service providers with increasing regularity and the stakes attached to them have changed significantly.

Annual penetration testing made sense in a different era. Infrastructure changed slowly. Applications had quarterly release cycles at best. The attack surface was mostly on-premises and well-defined. Running a pentest once a year gave organizations a reasonable snapshot of their security posture because that posture did not change dramatically between tests.

Before an attacker touches a single system, they search. They search Google, LinkedIn, GitHub, breach databases, and DNS records. They look through job postings, conference talks, and developer forums. They build a detailed picture of your infrastructure, your technology stack, your employees, and your security gaps, using nothing but publicly available information and tools that anyone can access for free.
