What is Credential Monitoring?
Credential monitoring is crucial in enterprise security. Your employees typically access dozens of business applications and systems. Password reuse across corporate and personal accounts is common. A single compromised credential can put your entire organization at risk. Data breaches often go undiscovered for months. This gives attackers plenty of time to exploit stolen credentials. They’ll use them for unauthorized access, move laterally through your network, and steal your data. By implementing credential monitoring, you can identify exposed credentials and reset passwords before they lead to a larger breach.

Frequently Asked Questions
Compromised credentials are login details like usernames, passwords, or authentication data such as session tokens that have been exposed, stolen, or leaked. Attackers use these credentials to gain unauthorized access to accounts. According to Verizon’s 2025 Data Breach Investigations Report, 88% of hacking breaches in 2024 were caused by stolen or brute-forced credentials. They’re frequently the initial access vector for data breaches and fraudulent activities.
Credentials get leaked in several ways. One common way is through third-party data breaches where hackers access a company’s database and steal user information. Other methods include phishing attacks where people are tricked into giving away their login details. Infostealer malware captures passwords directly from devices. Sometimes weak or reused passwords are guessed through brute force or credential stuffing attacks. Once leaked, credentials often end up on the dark web or in public forums where they can be sold or shared.
Data leakage occurs when sensitive information is intentionally or unintentionally exposed to unauthorized parties. It can happen through insecure databases, misconfigured cloud storage, insider threats, or malware. Data leakage puts personal, financial, or proprietary data at risk. You can prevent data leakage by continuously monitoring sensitive data, maintaining accurate attack surface management, training employees, and implementing technical controls.
Use a password manager to generate unique passwords for every account. Enable multi-factor authentication everywhere. Deploy Single Sign-On (SSO) solutions to reduce the number of credentials employees need to manage. Regularly monitor for password breaches. Reset compromised credentials as soon as they’re detected. Implement technical controls to prevent human error. Train employees to recognize phishing attempts.
Breachsense continuously monitors for your organization’s compromised credentials and data leaks across multiple sources. These include the dark web, criminal marketplaces, paste sites, public data leaks, Telegram channels, and hacker forums. When relevant data is identified, Breachsense sends an actionable alert with contextual details. This lets your security team mitigate the risk before attackers exploit the data.
