NordStellar: Proactive Threat Exposure Management

Data breaches pose a constant threat to businesses. Criminals often use stolen data from past leaks sold on the deep and dark web.

Unfortunately, most companies remain unaware of a leak for months. The average combined time to identify and contain a breach exceeds six months, a period where significant damage can occur.

To address this, Nord Security, the company behind NordVPN, created NordStellar. This new platform helps businesses manage threat exposure with proactive detection and response to cyber threats.

It provides businesses with the power to find threats before they escalate, securing data and helping prevent attacks.

The challenge of external threats

The risk of external attacks is growing. Account takeover attempts surged 21% in the past year (H1 2024 to H1 2025) and have skyrocketed 141% since 2021. This trend is often fuelled by human factors like stolen passwords and social engineering, which contribute to 60% of breaches. 

A single employee's compromised account can create a chain reaction that leads to ransomware attacks and data loss.

For many organisations, the effort to monitor these threats is a major challenge that requires a significant investment in time and people.

How NordStellar provides actionable security

NordStellar scans the internet’s hidden corners. It monitors dark web forums, marketplaces, and chat groups to turn raw threat data into clear, actionable intelligence that improves security.

The platform monitors a company’s leaked information, including employee credentials and customer data. If a leak is found, the company's team receives an alert and can take immediate action, like a forced password update to block unauthorised access.

This allows businesses to focus protection on their most critical assets, including the data of C-level executives and key stakeholders.

Cybercriminals can also steal active session cookies to bypass login screens and multi-factor authentication. To counter this, NordStellar monitors for these stolen cookies 24/7 and compares them against a reference set of hundreds of billions of cookies.

When the platform finds a compromised cookie, it sends an alert so security teams can invalidate the stolen session and prevent session hijacking.

NordStellar replaces the slow, manual process of inventory and scanning for external assets, which include domains, subdomains and IP addresses. The platform continuously scans these assets for vulnerabilities and provides alerts on open ports and other risks. This process provides an accurate and up-to-date view of your security posture.

The platform also tracks keywords related to your business across thousands of dark web sources.

This intelligence provides an early warning of planned attacks or data leaks, as tams can see the original posts where your company is mentioned. Organisations` can then use this information to prepare and prevent incidents.

A platform built on trust and experience

NordStellar has access to a huge data pool that includes over 40,000 dark web sources and 90 billion breached accounts. This wealth of information helps a team make informed decisions and supports compliance with regulations like NIS 2 and ISO 27001.

The setup process is straightforward and includes a dedicated account manager for assistance. Companies can receive alerts through their dashboard, Slack, email or other channels. The platform also features API integrations, which allow NordStellar to be integrated to existing SIEM or SOAR systems.

For organisations that want to move from a reactive to a proactive security model, NordStellar provides the necessary tools. Nord Security uses NordStellar to protect its own business, so the tool is tested and trusted in real-world conditions.
