What is NordStellar?

NordStellar is a threat exposure management platform designed to proactively detect and respond to online threats targeting companies. It was developed by the company behind NordVPN, which is also known for products like the password manager NordPass, network access security solution NordLayer, encrypted cloud storage NordLocker, and Saily eSIM.

Guided by the slogan “Know what hackers know,” NordStellar helps organizations safeguard sensitive data, protect user accounts, prevent fraud, and reduce ransomware risk before cyberthreats turn into something serious.

NordStellar works by scanning the dark and deep web 24/7 and looking for leaked information tied to your company. The sources include various dark web communities such as forums, marketplaces, and Telegram channels.

In addition to monitoring cybercriminal spaces, NordStellar also continuously maps and assesses your organization’s external attack surface. This helps identify vulnerable assets and misconfigurations before attackers can exploit them.

When a threat is detected, NordStellar delivers real-time alerts with detailed context. These alerts can include the source of the exposure, related assets, risk level, and recommended actions. Your security team receives notifications through preferred channels like Slack or email, which enables fast, informed responses and better decision-making.

Why is it important to monitor for data leaks?

When it comes to data breaches, reactive measures are no longer enough to protect your company from the consequences associated with it.

According to IBM’s report, it takes around six months for a company to become aware that its data has been exposed. As a result, businesses are often unable to respond quickly and only begin taking action when the damage has already been done.

The consequences following a data breach are serious. For example, as reported by IBM, the global average cost of a data breach in 2024 was $4.88 million — a 10% increase from the previous year. These financial losses often include expenses related to incident investigation, legal representation, regulatory fines, customer notification, and system recovery. Besides the financial toll, there are operational disruptions, reputational damage, and legal struggles, which can take years to overcome.

That’s why proactive data leak monitoring tools like NordStellar are essential. They allow organizations to shift from a reactive approach to a proactive one. By continuously scanning the deep and dark web for exposed data, NordStellar enables your security team to take action before attackers can exploit vulnerabilities.

Instead of responding after a breach has already caused harm, you can detect risks early and mitigate them before they escalate, significantly reducing both impact and response time.

What features does NordStellar offer?

The main features offered by the NordStellar threat exposure management platform include:

• 24/7 dark and deep web monitoring
• Data breach monitoring
• Account takeover prevention
• Attack surface management
• Session hijacking prevention
• AI-driven cybersquatting detection
• Real-time alerts about threats

Dark web and data breach monitoring

NordStellar helps you detect cyberthreats early by monitoring the deep and dark web 24/7. It scans over 20,000 sources, including hacker forums, dark marketplaces, Telegram channels, and ransomware blogs. You gain visibility into where cybercriminals plan, share, or sell stolen data — often before any attack begins.

The platform tracks various keywords linked to your business. These can include your company name, executive names, or product terms. When a match is found, NordStellar sends real-time alerts. Your security team is informed immediately and can act before any damage is done.

Such leaked information can include:

• Passwords
• Online and bank account login details
• Corporate email addresses
• Intellectual property
• Financial records
• Client and partner information
• Business contracts and legal documents
• Employee records

Moreover, NordStellar’s data breach monitoring tool provides in-depth insights into the threats. It shows when and how a breach happened, what type of data was exposed, and how serious the threat is. Any data leaks detected are categorized by risk level (Critical, High, Medium, or Low) so your team can respond based on urgency.

This visibility is critical. Without it, compromised accounts or leaked data can circulate unnoticed, giving attackers time to exploit your business. Dark web monitoring closes that gap. It helps you detect exposed credentials, vendor issues, or early signs of targeting, so you can respond before a threat escalates.

Account takeover prevention

An account takeover is a type of cyberattack where criminals use stolen login credentials to gain unauthorized access to user accounts — usually to steal data, commit fraud, or launch further attacks. These credentials are frequently obtained through phishing, data breaches, or purchased in bulk from the dark web.

Account takeovers are one of the most common and damaging cyberattacks today. NordStellar helps you stop them before they happen. It monitors the deep and dark web for stolen credentials and cross-checks them against your employee, customer, and partner accounts. If a match is found, your team is alerted before the credentials can be misused.

This protection is seamlessly integrated into your platform’s login, registration, and password reset processes. It prevents the use of breached passwords in real time, blocking attackers at the point of entry.

To go even further, NordStellar uses password fuzzing technology. It analyzes exposed credentials and generates common variations based on known hacking patterns. This stops predictable passwords from slipping through and strengthens your defenses against future attacks.

Session hijacking prevention

It’s a low-profile method of attack, yet one of the most dangerous. It allows attackers to take over active user sessions by stealing session cookies — temporary files that store authentication data. These cookies can bypass even strong defenses like two-factor authentication, making them a valuable target for cybercriminals.

NordStellar helps you stop session hijacking at the source. It continuously scans the deep and dark web for stolen session cookies linked to your organization. When a match is detected, the platform immediately alerts your team with key details, including the source, device, and associated data.

To neutralize the threat, NordStellar also revokes compromised sessions in real time. This prevents attackers from using stolen cookies to access your systems and protects users from unauthorized activity.

AI-driven cybersquatting detection

Cybersquatting is the practice of registering or using domain names that closely resemble a legitimate brand to deceive users, steal data, or profit by selling the domain back to the trademark owner. These domains may look nearly identical to your official site but are used for phishing, malware distribution, or other fraudulent activity.

NordStellar helps you detect and stop these threats early. Its AI-powered cybersquatting detection system continuously monitors the internet for suspicious domain registrations and changes. It uses visual and content similarity analysis to flag domains that attempt to imitate your brand.

Each suspicious domain is assessed using AI models that identify the threat type, severity, and intent. Whether it’s a phishing site or a fake login page, you receive real-time alerts with rich context, including screenshots, redirect paths, WHOIS data, and similarity metrics.

This level of visibility allows your team to act quickly and confidently. With case tracking and detailed evidence provided, NordStellar helps you protect your brand, users, and reputation from domain abuse.
