Cybersecurity in Healthcare: Protecting Patient Data in the Age of AI, IoMT, and Ransomware

Over the past decade, the global healthcare sector has undergone a sweeping digital transformation. Electronic Health Records (EHRs) moved to the cloud, hospitals adopted remote telemetry systems, pharmacies automated workflows, and AI-powered diagnostics entered day-to-day clinical practice. The result is a faster, more connected, and more data-rich healthcare ecosystem. But this connectivity has a cost.

Why Reg S-P Compliance Is Becoming a Critical Risk for Financial Firms - and How Nightfall Can Help

In finance, protecting customer data isn’t just good practice. It’s a regulatory mandate. The SEC’s Regulation S-P (Privacy of Consumer Financial Information) requires financial firms to guard against unauthorized access, maintain robust data-disposal practices, and have a formal incident response program. As the threat landscape has evolved, so has the regulation. This all means one thing: complacency is no longer an option.

Maximizing Microsoft Sensitivity Labels in Purview, SharePoint and other Microsoft 365 apps

Data governance and protection are crucial in safeguarding sensitive information. Proper classification and data labeling are essential to ensure that the right people access the right information. Failure to implement these practices can result in data breaches, financial losses, and reputational harm. To help with this, Microsoft offers sensitivity labels that classify and protect data as part of the compliance and security capabilities of Microsoft Purview Information Protection in Microsoft 365.

Enhancing Protection with Data Security Posture Management Tools

In the digital age, businesses face increasing pressures to safeguard their sensitive information. Leveraging effective data security posture management tools is crucial for mitigating risks and enhancing the overall security framework of an organisation.

CMMC and CUI Compliance Glossary: Key Terms and Phrases

Starting November 10, Phase 1 of the US Department of Defense’s CMMC 2.0 program went into effect, marking the start of a phased three-year rollout. Phase 1 begins with Level 1 and 2 self-assessments and culminates with the full implementation of program requirements in Phase 4. Organizations that fail to demonstrate compliance will not be eligible to bid on U.S. Defense contracts.

Shadow AI: From Hidden Threat to Organizational Challenge

This blog post is adapted from a recent episode of The Cloudcast podcast featuring Rohan Sathe, CEO and co-founder of Nightfall AI. Listen to the full conversation here. Your employees are uploading company documents to ChatGPT. Your healthcare teams are transcribing sensitive call recordings and feeding them into LLMs. Your finance department is pasting confidential spreadsheets into publicly accessible AI tools. And unless you have visibility into these workflows, you have no idea it's happening.

Why Removing Document Metadata Matters

Most people consider a document only as words, numbers, and images that are presented on their screen. They think that when they export a file to PDF or attach it to an email, what is visible is all that exists. However, digital documents have a lot more information beneath the surface that are not visible to the casual eye but can be easily accessed by anyone who knows how to find them. The hidden layer of a document is called metadata, and it is much more important in data security than a lot of organizations acknowledging.

Comparing NER Models for PII Identification

Identifying and redacting personally identifiable information (PII) is a critical need for enterprises handling sensitive data. Over 1000 NLP models and tools claim to solve this problem, but an infinite number of options opens a paradox of choice. We compiled this comprehensive comparison that examines ten notable PII detection solutions – their features, use cases, pros/cons, and reported success rates.

The Business Case for DSPM: Reducing Risk Through Continuous Visibility

Similar to many other industries today, modern IT is so complex. In the contemporary world, companies are dealing with data within cloud, on-premise, and hybrid environments. This complexity brings about serious security challenges that cannot be solved by conventional security tools. The solution is DSPM (data security posture management); it offers full-time visibility to your data. This will enable you to identify weak spots before an attack. It also assists you in staying secure and compliant and safeguarding your data.

E-Commerce Security: A Complete Guide to Protecting Your Online Store

When you shop online, you trust the website with your most personal information-your name, address, and credit card details. And if you expect safety as a customer, imagine how much responsibility an online store owner carries. That's why e-commerce security isn't just another technical task-it's the foundation of keeping your customers safe and your business trustworthy.

When Collaboration Tools Become Exfiltration Channels: What the Palantir Case Reveals

Last week, Palantir filed a lawsuit in Manhattan federal court alleging that two former senior engineers used Slack to transfer confidential documents - including healthcare demonstration frameworks, revenue cycle diagrams, and customer deployment plans - the day after one of them gave notice. The documents were allegedly accessed later on a personal phone. The engineers had since joined Percepta, a competing AI startup backed by General Catalyst that emerged from stealth mode in October.

Embracing Zero Trust: Lessons from Australia's Defence Supply Chain Data Breach

Earlier this week, The Australian broke the news that the Cyber Touhan hacking group stole classified plans for Australia’s new infantry fighting vehicles, a $7B AUD procurement program, in a massive cyber-attack targeting 17 Israeli defence contractors in the supply chain. The attack was carried out by targeting a downstream supplier, MAYA Technologies, exploiting vulnerabilities in their network and peripherals to gain access to sensitive data.

AI Browsers Are Silently Exfiltrating Sensitive Data - and Legacy DLP Can't See It

A new class of AI-powered browsers are rewriting the rules of data security. While CISOs focus on traditional vectors, employees are unknowingly creating permanent backdoors to your most sensitive data through browsers that remember everything, sync everywhere, and share it all with AI models. The bottom line: If you're not actively protecting against AI browser exfiltration, you're already leaking data. Here's why it's happening, what it costs, and how to stop it today.

From Cyberhaven to Nightfall: A Practical Migration Blueprint for Modern DLP

As organizations evaluate modern DLP solutions, the gap between vendor promises and operational reality becomes critical. Through analysis of organizations running Cyberhaven - including several evaluating migration to Nightfall - we've discovered systematic challenges that impact security effectiveness, operational efficiency, and business productivity. This analysis provides CISOs and security leaders with crucial insights for making informed DLP decisions.

Data classification and DLP: Prevent data loss, prove compliance

A successful data security strategy isn’t about one tool, it’s about a sequence of steps. The first is understanding your data. The second is controlling how it moves. Together, classification and DLP create a data security foundation that prevents data leaks and breaches without slowing down the business. Unlike point tools, modern data classification solutions continuously scan repositories in real time, ensuring new files and updates are labeled correctly as your environment changes.
