What is EASM?

Gabriela Silk — Thu, 26 Mar 2026 17:52:03 GMT

Every organization has a digital presence on the public internet. Domains, subdomains, cloud services, APIs, web applications, exposed ports…the list grows constantly, and also often faster than security teams can track.

But somewhere in that sprawling digital footprint, there is almost certainly something that should not be exposed. A forgotten subdomain from a project that wrapped up two years ago. A cloud storage bucket someone spun up and never locked down. A legacy system that IT retired internally but never fully took offline.

Those overlooked assets are exactly what attackers go looking for. External Attack Surface Management (EASM) is the discipline that is built to find them first.

ISO 27001 Certification: What is it?

Due to the trust it builds with customers and stakeholders, the reduction of security risk, and its introduction of operational discipline and scalability, ISO 27001 has become one of the most valuable certifications a business can hold. Understanding what it is and why it matters is vital for organizations that handle sensitive information.

Continuous Testing: What is it?

Gabriela Silk — Thu, 26 Mar 2026 17:50:44 GMT

Software development has never moved at a faster pace. Release cycles that were once stretched across quarters have compressed into weeks. Sprints that used to feel aggressive are now baseline. And customer expectations for stable and bug-free software have not gotten more forgiving alongside that acceleration. If anything, they have gotten less so. In that environment, testing cannot be an afterthought sitting at the end of the pipeline. It has to be woven into every stage of how software gets built.

That is the core idea behind continuous testing. Not testing as a phase you reach after development wraps up, but testing as a constant and automated pulse that is running through the entire software development lifecycle. Organizations that implement continuous testing effectively are often able to ship higher-quality software faster. The ones that are still treating testing as a final checkpoint, however, are experiencing the limitations of that model in production environments.

In The News: Prescient Security Achieves Authorized C3PAO Designation

Gabriela Silk — Thu, 12 Mar 2026 17:41:56 GMT

Nashville, Tennessee – March 12, 2026 – Prescient Security, a global leader in cybersecurity and audit services has successfully achieved Authorized C3PAO Designation, authorized by the Cybersecurity Maturity Model Certification (CMMC) Accreditation Body (The CyberAB) as a CMMC Third-Party Assessment Organization (C3PAO). This authorization strengthens the firm’s ability to deliver comprehensive CMMC services that enable clients to prepare and obtain certification.

The Cybersecurity Maturity Model Certification (CMMC) is a major Department of Defense (DoD) program built to protect the defense industrial base (DIB) from increasingly frequent and complex cyber-attacks. It aims to enhance the protection of controlled unclassified information (CUI) and federal contract information (FCI) shared within the DIB. CMMC is designed to provide DoD increased assurance that a DIB company can adequately protect sensitive CUI and FCI, accounting for information flow down to subcontractors in a multi-tier supply chain. All DoD prime- and sub-contractors planning to bid on future contracts with the CMMC DFARS clause will be required to obtain a CMMC certification prior to contract award.

What is NIST 800-53?

Gabriela Silk — Thu, 05 Mar 2026 20:30:37 GMT

For anyone who is working in cybersecurity auditing, federal IT systems, or government contracting, NIST 800-53 is a foundational piece of the professional landscape. It is one that shapes how security decisions get made, how systems get assessed, and also how organizations demonstrate that they're taking data protection seriously.

NIST 800-53 exists to solve the genuinely difficult problem of securing information systems in a consistent and measurable way when sophisticated adversaries are actively trying to compromise them. Read below to learn NIST 800-53's origin, purpose, and how organizations can leverage it for a comprehensive security posture.

What is Governance, Risk, and Compliance (GRC) in Cybersecurity?

Gabriela Silk — Fri, 27 Feb 2026 17:39:54 GMT

Today, cybersecurity programs are under unprecedented pressure. Organizations are dealing with increased attack surfaces, more advanced adversaries, rigorous regulatory requirements, and intense scrutiny from boards and regulators. Security can no longer solely be a technical concern about controls and tooling. It needs to function as a business enabler, embedded in the corporate strategy, as well as risk tolerance and legal obligations.

This is where Governance, Risk, and Compliance (GRC) come in. GRC establishes the structural framework to create alignment between cybersecurity initiatives and business objectives. It mitigates uncertainty through systematic risk management practices and ensures adherence to regulatory and contractual obligations.

Governance, Risk, and Compliance are not treated as discrete functions, especially in more mature organizations. Instead, organizations integrate them in a single operating model that promotes accountability, resilience, and measurable assurance. For security leaders, auditors, and risk professionals, GRC is not simply overhead. It is the means to make cybersecurity a disciplined enterprise risk management program (and not just a reactive defense).

Security Risk Mitigation: What is it?

Gabriela Silk — Thu, 26 Feb 2026 21:55:29 GMT

Organizations today operate in an environment where cyber threats are constant, evolving, and increasingly sophisticated. From ransomware attacks that halt operations to data breaches that expose millions of customer records, the consequences of poor security practices are both immediate and long-lasting. Cyber incidents no longer represent rare disruptions; they are operational realities that every organization must anticipate.

Vulnerability and Patch Management

Gabriela Silk — Wed, 25 Feb 2026 19:40:47 GMT

Modern enterprise environments operate under continuous exposure to software defects, misconfigurations, and emergent exploit techniques. Attackers industrialize vulnerability discovery and weaponization, often integrating newly disclosed flaws into exploit kits within hours. As a result, organizations must treat system hygiene as an operational discipline rather than an occasional maintenance task. Two core practices anchor this discipline: patch management and vulnerability management.

Although frequently conflated, these processes serve distinct but interdependent functions. Patch management focuses on remediating known defects through vendor-provided fixes, while vulnerability management identifies, evaluates, prioritizes, and orchestrates the remediation of broader weaknesses across the technology stack. Mature cybersecurity and audit programs recognize that resilience emerges only when both practices operate in concert, supported by governance, metrics, and accountability.

Industry experts consistently frame these capabilities as foundational security controls rather than optional enhancements.

Secure Code Review

Gabriela Silk — Wed, 25 Feb 2026 19:16:25 GMT

Modern software systems function in the heart of almost all business. Everything from financial services and healthcare platforms to critical infrastructure and cloud-native applications all run on modern software systems. In the era of Agile and DevOps practices, developers write and deploy code quicker than ever to speed up development. Unfortunately, speed without security brings security risks. Vulnerabilities created during development also tend to propagate into production and can lead to very costly, dangerous, and occasionally catastrophic data breaches.

Data breaches, ransomware incidents, and supply-chain attacks frequently trace back to insecure code rather than failures in firewalls or perimeter defenses. Attackers increasingly exploit logic flaws, improper input validation, broken authentication mechanisms, and insecure dependencies embedded directly in applications. To avoid pushing insecure codes into production environments, organizations must adopt proactive practices that identify weaknesses before release rather than reacting after compromise.

What Is a Compliance Audit?

Gabriela Silk — Wed, 25 Feb 2026 19:10:49 GMT

Modern security controls, while technically robust, are insufficient on their own. Regulators, customers, and boards increasingly require documented assurance that controls are designed, implemented, and operating effectively. This is where a compliance audit comes in.
