Recruitment is evolving, and so are the risks tied to it. Today, an Applicant Tracking System (ATS) has become more advanced than ever, streamlining hiring processes and managing vast amounts of sensitive information shared by candidates. However, with this convenience comes a growing concern: data security.
Every job application contains sensitive information: names, addresses, employment history, and even financial details. If an ATS is not secured properly, this data becomes vulnerable to cyber threats, breaches, and compliance violations. The stakes are high—not just for businesses but for the candidates trusting them with their personal information.
So, how secure is your ATS? Are you confident that your system is protecting candidate data while staying compliant with evolving regulations like GDPR and CCPA?
In this blog, we’ll break down the biggest security risks in ATS platforms, explore best practices for protecting recruitment data, and discuss what the future holds for cybersecurity in HR. Let’s get started.
The Evolving Threat Landscape in 2025
Cyber threats are evolving and becoming more and more advanced. With the kind of information the recruitment industry deals with, Applicant Tracking Systems (ATS) are increasingly becoming a target. As businesses rely more on digital hiring solutions, cybercriminals are finding new ways to exploit vulnerabilities in recruitment platforms.
In 2025, the risks are becoming higher than ever.
1. Rising ATS Cyberattacks
Hackers are no longer just after financial data—they’re targeting candidate information stored in ATS platforms. Phishing attacks, ransomware, and data breaches are becoming more sophisticated, often exposing thousands of job seekers to identity theft and fraud.
2. Insider Threats and Unauthorized Access
Not all threats come from external hackers. Insider threats—whether malicious or accidental—pose a major risk. Weak access controls can allow unauthorized employees or third-party vendors to view, misuse, or leak sensitive recruitment data.
3. Compliance Risks and Regulatory Challenges
With stricter data privacy laws like GDPR, CCPA, and AI Act emerging, companies must ensure full compliance or face heavy fines. Many organizations still struggle to implement proper data encryption, consent mechanisms, and secure storage in their ATS.
4. AI and Automation Risks
While AI-driven recruitment tools improve efficiency, they also introduce new vulnerabilities. Poorly secured AI models can be manipulated, leading to biased hiring decisions, data leaks, or even AI-driven phishing attacks that trick recruiters into granting unauthorized access.
5. Third-Party Integrations: A Hidden Risk
Many ATS platforms integrate with background check services, assessment tools, and HR management software. If these third-party systems lack strong security measures, they can become an entry point for cybercriminals, compromising your entire recruitment ecosystem.
What This Means for Businesses
Companies can no longer afford to treat ATS security as an afterthought. The risks are real, growing, and potentially devastating—not just in terms of financial penalties but also in the loss of candidate trust and brand reputation.
In the next section, we’ll dive deeper into key data security concerns in ATS and how organizations can address them.
Key Data Security Concerns in ATS
Businesses handling large volumes of candidate data must be aware of key security risks that could lead to data breaches, compliance violations, and loss of trust. Here are the biggest concerns:
1. Data Encryption: Protecting Candidate Information
Without strong encryption, candidate data such as resumes, personal details, salary expectations, and employment history becomes vulnerable to cyber threats and potential breaches. Hackers can intercept this sensitive information, leading to privacy violations and compliance risks.
To mitigate this, businesses should opt for an Applicant Tracking System (ATS) that offers end-to-end encryption, ensuring that both stored and transmitted data remain secure and unreadable to unauthorized parties. This proactive approach safeguards candidate information, enhances trust, and aligns with data protection regulations.
2. Access Control & Authentication: Who Has Permission?
Weak access controls can expose sensitive information to unauthorized individuals, increasing the risk of data leaks, manipulation, or misuse. Even insider threats, whether intentional or accidental, can compromise data security and lead to significant breaches.
To mitigate these risks, organizations should implement Role-Based Access Control (RBAC) to ensure that only authorized personnel have access to specific data based on their job roles. Additionally, Multi-Factor Authentication (MFA) adds an extra layer of security by requiring multiple verification steps before granting access. These measures help protect candidate information, prevent unauthorized modifications, and strengthen overall Applicant Tracking System (ATS) security.
3. Compliance & Regulatory Risks
Laws like GDPR, CCPA, and the AI Act mandate that companies handle candidate data responsibly, ensuring privacy, transparency, and security throughout the hiring process. Failure to comply with these regulations can lead to heavy fines, legal consequences, and reputational damage, making compliance a critical aspect of ATS security.
To mitigate these risks, organizations should choose an ATS provider that adheres to global data protection standards and offers essential compliance features such as automated data retention policies, consent tracking, and audit logs. These measures help maintain regulatory alignment, protect candidate privacy, and build trust in the recruitment process.
4. Third-Party Integrations: A Weak Link
Many Applicant Tracking Systems (ATS) integrate with background check services, payroll systems, and other HR tools to streamline recruitment, but these third-party connections can also introduce security vulnerabilities. If external services lack proper security measures, they create potential entry points for cyber threats, putting sensitive candidate data at risk.
To mitigate this, organizations should work only with trusted vendors, conduct regular security audits, and implement strong API security measures to ensure that integrations do not compromise data protection. Strengthening these security controls helps prevent breaches and ensures a safer, more reliable recruitment process.
5. Data Retention & Deletion Policies
Storing candidate data indefinitely increases security risks, as outdated or unnecessary information becomes an easy target for cyberattacks and potential data breaches. Additionally, retaining data longer than necessary can lead to compliance violations under regulations like GDPR and CCPA, which require organizations to manage personal data responsibly.
To minimize these risks, companies should implement automated data retention policies that regularly delete outdated or irrelevant candidate information in accordance with privacy laws. This proactive approach not only enhances data security but also ensures compliance and reduces unnecessary data exposure.
6. AI-Driven Risks in ATS
AI-powered resume screening and automated hiring decisions are revolutionizing recruitment, but without proper security measures, they can introduce risks such as bias, data manipulation, and breaches. Poorly designed AI systems may unintentionally favor certain candidates over others, while cyber threats like data poisoning attacks can compromise the integrity of hiring decisions.
To mitigate these risks, organizations should choose an ATS that audits AI decision-making, ensures transparent and ethical AI usage, and implements robust security measures to protect against data tampering. By prioritizing AI security and fairness, companies can maintain trust and integrity in their recruitment processes.
What Businesses Should Do Next
Understanding these security concerns is the first step. The next? Implementing best practices to secure your ATS against cyber threats. In the following section, we’ll explore effective strategies for protecting applicant data and ensuring compliance with evolving regulations.
