The healthcare industry in 2025 is under attack, with 93% of organizations reporting cyberattacks in the past year. These breaches have compromised the protected health information (PHI) of 259 million Americans and disrupted patient care in nearly three-quarters of U.S. healthcare facilities. Cybercriminals are targeting healthcare because stolen medical records are worth 10x more than credit card data, making this sector a prime target.
Key challenges include:
- Ransomware attacks that delay surgeries and disrupt care.
- Vulnerabilities in Internet of Medical Things (IoMT) devices like insulin pumps and MRI machines.
- Weak security among third-party vendors, with 80% of stolen data linked to these entities.
- Lack of basic safeguards: 37% of organizations don’t use multifactor authentication, and 51% lack endpoint detection tools.
The financial toll is staggering, with $9.77 million per phishing breach and $12.84 million in HIPAA fines in 2024 alone. Beyond costs, these attacks erode patient trust and endanger lives.
What’s the solution?
- Stronger access controls: Multifactor authentication, role-based access, and privileged access management.
- Encryption: Protect data in transit and at rest, especially in cloud systems and IoMT devices.

Healthcare Cybersecurity Trends in 2025
Healthcare cybersecurity in 2025 revolves around three key areas: the rise of connected medical devices, AI-driven threat detection, and a proactive shift toward preventing attacks before they happen. These trends bring both challenges and opportunities, shaping how healthcare organizations approach security.
Growth of IoMT and Connected Medical Devices
The Internet of Medical Things (IoMT) has revolutionized healthcare with devices like insulin pumps, cardiac monitors, and smart hospital beds. While these tools improve patient care, they also create serious security risks. These devices handle sensitive patient data and perform critical functions, making them attractive targets for cyberattacks.
Hospitals often manage thousands of devices, many of which are older systems with outdated security protocols. This mix of legacy and modern equipment creates vulnerabilities. A single hospital might use devices from dozens of manufacturers, each with its own security standards, leading to gaps that attackers can exploit. For example, an MRI machine linked to imaging systems and patient records could serve as an entry point for hackers to access broader hospital networks.
To counter these threats, healthcare organizations are adopting strategies like network segmentation to isolate medical devices from other IT systems. They’re also creating detailed inventories to track every device, its software version, and update status. This process often uncovers forgotten or unauthorized devices that pose hidden threats.
Manufacturers are improving device security by adding features like encrypted communication, secure boot processes, and over-the-air updates. However, hospitals will need to manage a mix of old and new devices for years to come, making compliance efforts essential to protect patient data. As these systems grow more complex, advanced analytics are becoming critical for spotting subtle signs of trouble.
AI and Automation for Threat Detection
Artificial intelligence (AI) has become a cornerstone of healthcare cybersecurity. Modern healthcare networks generate an overwhelming amount of data - millions of logs, connections, and actions every day. AI systems can analyze this data in real time, identifying unusual patterns that might signal a threat.
For instance, machine learning can establish normal network behavior and flag anomalies, like a nurse’s credentials being used to access records at an odd hour or from an unexpected location. These systems can also contain threats like ransomware by isolating compromised devices or blocking suspicious activity before it spreads.
AI isn’t just about detecting threats - it’s also transforming compliance processes. Healthcare organizations must constantly monitor and document adherence to regulations, from encryption practices to access controls. AI tools can automate these tasks, scanning for compliance gaps and generating reports faster than manual methods. Natural language processing can even analyze policies and incident reports to suggest updates.
Despite its benefits, AI isn’t a standalone solution. It requires careful calibration to avoid false alarms that overwhelm security teams or, worse, missing real threats. The quality of AI depends on its training data, and these systems must also be protected from tampering. The most effective strategies combine AI’s speed and precision with human expertise, allowing security professionals to focus on complex investigations and planning.
Moving from Reactive to Preventive Security
Healthcare organizations are shifting from reacting to attacks after they happen to preventing them altogether. This proactive approach uses continuous monitoring and predictive analytics to identify vulnerabilities before they can be exploited. Automated tools now scan for weaknesses and policy violations around the clock, helping security teams address risks as soon as they arise.
Threat hunting has also become a key part of preventive security. Instead of waiting for automated alerts, teams actively search for early signs of compromise. This approach pairs well with a zero trust model, which verifies every access request to ensure security without compromising clinical workflows. Techniques like microsegmentation and just-in-time access help balance strong security with the fast, flexible access healthcare professionals need.
Another critical element of preventive security is training healthcare staff. Employees are often targeted by phishing and social engineering attacks, so regular simulations and tailored training sessions help build a stronger security culture. When everyone understands their role in protecting patient data, the entire organization becomes more resilient.
Major Cybersecurity Threats Facing Healthcare in 2025
The healthcare industry is navigating an increasingly complex cyber threat landscape, where attacks not only compromise sensitive data but can also disrupt patient care. As trends like IoMT (Internet of Medical Things) and AI-driven detection shape defense strategies, understanding how cybercriminals exploit vulnerabilities is essential for building effective safeguards.
Ransomware Attacks and Data Extortion
Ransomware remains one of the most pressing threats to healthcare organizations. Hospitals and medical facilities are prime targets because any downtime can have serious implications for patient care. Unlike other industries, where delays might be inconvenient, disruptions in healthcare can directly impact lives.
Modern ransomware attacks often follow a double extortion model. Attackers encrypt critical systems and simultaneously steal sensitive patient data, threatening to release it unless a ransom is paid. The financial toll of these attacks can be staggering, encompassing system restoration, forensic investigations, legal fees, regulatory fines, patient notifications, and revenue losses.
Beyond the financial cost, ransomware has a direct impact on patient care. Hospitals may be forced to revert to paper records, delay procedures, and reallocate staff to manage the crisis. Emergency departments, labs, and pharmacies often struggle without access to digital records, leading to delays and potential errors that can jeopardize patient outcomes.
Attackers have also become more strategic, often conducting reconnaissance to identify weak points and timing their strikes during holidays or periods of reduced IT staffing. They exploit vulnerabilities in medical software, unpatched systems, and misconfigured remote access tools, using multiple entry points to maximize their impact.
Third-Party and Supply Chain Risks
Healthcare organizations rely heavily on third-party vendors, business associates, and service providers, many of whom have access to sensitive systems and patient data. This interconnectedness creates significant vulnerabilities, as a single compromised vendor can provide attackers with a backdoor into multiple networks.
Supply chain attacks are particularly concerning because they bypass internal security measures by exploiting trusted relationships. Hospitals often work with numerous partners, each bringing its own security practices and risk levels. Smaller vendors, in particular, may lack the resources to implement robust cybersecurity measures, even when managing sensitive data or maintaining network access.
Software supply chains add another layer of complexity. Healthcare systems depend on electronic health records, medical imaging software, and laboratory applications, each of which can introduce vulnerabilities if patches or updates are delayed. As organizations move more data to the cloud, ensuring that cloud providers meet stringent security standards becomes critical.
Medical devices present unique challenges as well. Many devices operate on proprietary or outdated systems, and developing patches for discovered vulnerabilities can take time. In some cases, older devices cannot be updated without voiding warranties or regulatory approvals, leaving hospitals with the difficult choice of using vulnerable equipment or investing in costly replacements.
Regulatory requirements, such as those under HIPAA, add further pressure. Healthcare organizations are responsible for safeguarding patient data, even when third parties are involved. This means conducting thorough due diligence, embedding strict security clauses in contracts, and continuously monitoring vendor compliance.
Phishing Campaigns and Insider Threats
Human error remains one of the biggest weaknesses in cybersecurity. Attackers frequently target healthcare employees with phishing schemes designed to steal credentials, deploy malware, or initiate fraudulent transactions.
Phishing campaigns have become increasingly sophisticated. Cybercriminals craft emails that mimic communications from hospital administrators, IT departments, or trusted vendors, often linking to fake login pages that capture credentials. Some campaigns exploit current events or organizational changes to appear more convincing.
Healthcare employees, who often work in high-pressure environments and require quick access to multiple systems, are particularly vulnerable. Irregular work hours and remote access arrangements can make it harder to spot suspicious activity.
A successful phishing attack can have severe consequences. Once attackers gain access to user credentials, they can navigate systems, escalate privileges, and exfiltrate sensitive data - often going undetected for long periods.
Insider threats also pose significant risks, whether intentional or accidental. Malicious insiders might sell patient data or sabotage systems, while accidental breaches can occur when employees mishandle information, such as sending sensitive data to personal email accounts or losing unencrypted devices.
Healthcare’s reliance on broad access to patient information - spread across doctors, nurses, specialists, administrative staff, and billing teams - makes managing insider threats particularly challenging. High staff turnover and the use of temporary workers further complicate access control.
Detecting insider threats requires monitoring user behavior to identify unusual activity, such as accessing records outside of one’s typical responsibilities or downloading large volumes of data. Monitoring systems must strike a balance between flagging genuine threats and avoiding unnecessary disruptions to clinical operations.
Creating a culture of security awareness is essential. When employees understand the importance of cybersecurity and feel empowered rather than micromanaged, they become active participants in protecting patient data. The evolving nature of these threats highlights the need for a comprehensive approach to cybersecurity in healthcare.
Practical Solutions for Healthcare Cybersecurity
Understanding the threats facing healthcare systems is only part of the equation. Organizations must implement solutions that reduce vulnerabilities while ensuring patient care remains uninterrupted. By combining technical safeguards, process improvements, and proactive planning, healthcare providers can significantly lower risks and meet compliance standards. These measures work together to strengthen the defenses discussed earlier.
Strengthening Access Controls
Effective access controls are critical for reducing exposure to cyber threats. By limiting access to sensitive systems and data, healthcare organizations can minimize breaches caused by unauthorized entry. Access control failures remain one of the top reasons for data breaches in healthcare, often due to excessive permissions granted to employees.
Multi-factor authentication (MFA) adds an extra layer of security by requiring users to verify their identity through an additional step, such as entering a code sent to their phone, using a biometric scan, or employing a hardware token. This approach significantly reduces the risk of compromised credentials. Prioritizing MFA for remote access, administrative accounts, and systems containing protected health information (PHI) is a must for healthcare organizations.
Role-based access control (RBAC) ensures employees can only access the data and systems relevant to their job. For instance, a billing specialist should not have access to clinical imaging systems, just as a radiologist has no need to view payroll databases. By mapping job roles to specific permissions and regularly reviewing access rights, RBAC helps reduce unnecessary exposure.
Privileged access management (PAM) focuses on accounts with elevated permissions, such as system administrators or database managers. Since these accounts have extensive control, they are prime targets for attackers. PAM tools enforce stricter authentication, monitor privileged sessions for unusual behavior, and maintain detailed logs. Additionally, just-in-time access tools can grant elevated permissions only when necessary and revoke them immediately afterward.
Continuous monitoring adds another layer of protection. Anomalies like logins from unexpected locations or access during unusual hours should trigger alerts for investigation. These measures, combined, form a strong foundation for a layered defense strategy.
Protecting Data with Encryption
Encryption is a cornerstone of data security, transforming information into a format that can only be deciphered with the appropriate key. For healthcare organizations handling PHI, encryption isn't just a best practice - it’s a regulatory requirement under frameworks like HIPAA and HITRUST.
"Data Encryption and Access Control: Encrypt PHI (protected health information) both during transmission and at rest, and limit access based on employee roles and departments." - Bluesight
Data in transit, such as patient records shared between a hospital and a specialist, must be encrypted to prevent interception. Data at rest, stored on servers, laptops, mobile devices, or backup systems, should also be encrypted to ensure that even if a device is stolen, the data remains protected without the decryption key.
Encryption failures can lead to devastating breaches. For example, in 2025, a major U.S. health insurance provider exposed 4.7 million PHI records over three years due to a misconfigured cloud storage bucket. The absence of encryption made the data immediately accessible to anyone who discovered the error.
"100% of the hacked data was not encrypted, either due to stolen credentials granting access to encrypted data or data being stored in an unencrypted format outside the EHRs." - John Riggi, National Advisor for Cybersecurity and Risk, AHA, and Scott Gee, Deputy National Advisor for Cybersecurity and Risk, American Hospital Association
Cloud storage introduces additional challenges. As more healthcare providers rely on cloud solutions, ensuring data is encrypted during transmission and storage is essential. Misconfigured cloud settings, such as unsecured storage or unencrypted databases, are among the leading causes of cloud-based breaches.
Medical devices further complicate encryption efforts. Many Internet of Medical Things (IoMT) devices lack robust encryption, leaving them vulnerable to interception and manipulation. When acquiring new equipment, healthcare organizations should prioritize devices that support strong encryption protocols and receive regular security updates.
Proper encryption key management is equally vital. Keys should be stored securely, separate from the encrypted data, with access tightly controlled and logged. Regular key rotation and contingency plans for key recovery are necessary to maintain security and ensure continuity in case of system failures. Encryption acts as the last line of defense when other security measures fall short.
Creating and Testing Incident Response Plans
Even with strong defenses, healthcare organizations must be ready for potential security incidents. An incident response plan provides a structured approach to detecting, containing, and recovering from cyberattacks, minimizing disruption to operations and patient care.
A solid incident response plan begins by defining what constitutes an incident and establishing clear escalation procedures. Not every alert demands the same response, so the plan should categorize incidents by severity and outline who needs to be notified at each stage. Specific roles - such as technical responders, legal advisors, communications specialists, and leadership - are assigned to ensure everyone knows their responsibilities during a crisis.
The plan should include detailed steps for handling common incident types, such as ransomware attacks, data breaches, or insider threats. These steps guide teams through containment, eradication, and recovery. Communication protocols are also crucial, specifying when and how to notify patients, regulators, law enforcement, and the media. For instance, HIPAA requires notification of affected individuals within 60 days for breaches impacting 500 or more people.
Tabletop exercises are an excellent way to practice incident response. In these simulations, teams work through realistic scenarios - like a phishing attack or a ransomware outbreak - under the guidance of facilitators. These exercises help identify weaknesses in the plan, such as outdated contact lists or untested backups, and build confidence in handling real incidents.
Beyond simulations, healthcare organizations should test their technical recovery capabilities regularly. This includes verifying that backups are functional and can be restored quickly, ensuring failover systems are operational, and confirming that incident response tools are properly configured. Frequent testing turns an incident response plan into a practical, actionable strategy.
In healthcare, where downtime can directly impact patient outcomes, having a well-prepared incident response plan can make all the difference. By combining readiness with compliance requirements, organizations can maintain strong cybersecurity while ensuring continuity of care.

Using Compliance Frameworks and Managed Services
Healthcare organizations face a dual challenge: keeping patient data safe while meeting tough regulatory standards. The stakes are high - not just legally, but also in terms of patient trust and operational focus. To tackle these challenges, many organizations turn to compliance frameworks and managed services, which provide structure and support without straining internal resources.
Understanding HIPAA, HITRUST, and NIST CSF
Three key frameworks dominate the healthcare compliance world, each addressing different needs but working well together to create a robust security program.
HIPAA (Health Insurance Portability and Accountability Act) sets the legal foundation for protecting patient data. Its Security Rule requires safeguards - administrative, physical, and technical - for electronic protected health information (ePHI). This includes risk assessments, access controls, data encryption, audit logs, and breach notification procedures. Failing to comply can lead to hefty fines and damaged reputations, making HIPAA compliance critical not just legally, but also for maintaining patient trust. However, HIPAA's flexibility in implementation can leave organizations searching for more specific guidance.
HITRUST CSF (Common Security Framework) builds on HIPAA by combining multiple standards, like NIST and ISO, into a certifiable framework tailored for healthcare. It simplifies compliance by addressing over 150 control objectives across 19 categories, including encryption, access control, and incident management. HITRUST certification signals to regulators, partners, and customers that an organization’s security measures meet rigorous standards. Many healthcare organizations now require their vendors to achieve HITRUST certification, making it a valuable benchmark.
NIST Cybersecurity Framework (CSF) provides a practical, risk-based approach structured around five core functions: Identify, Protect, Detect, Respond, and Recover. While originally designed for critical infrastructure, NIST CSF has been widely adopted in healthcare due to its actionable guidance. It complements HIPAA by offering structured processes for tasks like risk assessments and incident response.
By combining these frameworks, healthcare organizations can create a layered approach: HIPAA sets the baseline, NIST CSF offers operational guidance, and HITRUST provides comprehensive controls with third-party validation. This strategy not only meets compliance requirements but also strengthens overall security. For organizations lacking the resources to manage these frameworks internally, managed services like Cycore offer a lifeline.
