Cybersecurity for complex IT and OT environments
Senior specialists, strengthened by AI
Healthcare organisations depend on availability, trust and patient safety. Hospitals, clinics, mental health providers, laboratories, elderly care organisations and healthcare platforms process sensitive medical data and rely heavily on digital processes. One vulnerability in identity, medical applications, cloud, SaaS, APIs or network segmentation can directly affect care continuity. Cybersecurity in healthcare therefore requires an approach that accounts for clinical processes, patient data and operational continuity.
Healthcare environments use EHR systems, PACS environments, laboratory systems, medical devices, mobile workstations, external healthcare portals and cloud platforms. These systems are often tightly connected. A vulnerability in one domain can affect access to patient records, care processes or diagnostics. The attack surface grows through SaaS, cloud, identity federation, API integrations and regional data exchange. Legacy systems also often remain in use longer because medical applications or devices depend on specific versions. This creates risk at the boundary between old and new technology, especially where administrative rights, integrations and network segmentation are not configured precisely.
DeepBlue helps healthcare organisations determine which risks are actually exploitable. Not only from a policy or compliance perspective, but from an attacker’s perspective. We examine how an attacker gains access, which privileges can be expanded, which systems can be reached and what impact is possible on care processes. AI and tooling support analysis, correlation and efficiency. The core remains technical expertise, attacker insight and demonstrable impact. Penetration tests make these risks concrete by validating attack paths in a controlled way and translating them into technical assurance, remediation priority and executive-grade insight.

Penetration testing in healthcare must prove more than technical vulnerabilities. The key question is which vulnerabilities are actually exploitable and what impact they can have on patient data, medical processes and care continuity. DeepBlue therefore tests from realistic attack paths. We examine identity environments, EHR integrations, healthcare portals, cloud platforms, APIs, network segmentation, external infrastructure and reachability of critical systems. We assess not only access, but also privilege escalation, lateral movement, data access, logging, detection and recovery options.
Our penetration tests are manual, deep and controlled. Senior specialists with experience in complex IT and OT environments execute the work. Tooling and AI support the analysis, but do not determine the outcome. The focus is on demonstrable impact, clear risk assessment and concrete remediation priority. Findings are mapped with CVSS, so technical teams can remediate precisely and executives understand where the greatest risk sits. DeepBlue is CCV Pentest certified and delivers independent, reliable and practical penetration test reports for healthcare organisations that need technical assurance over digital resilience.
Ransomware is one of the most critical threats to healthcare organisations. Attackers gain administrative privileges, sabotage backups, evade detection and encrypt systems. Outages in EHR, imaging, scheduling or laboratory systems directly cause delayed care, emergency procedures and increased patient safety risks.
Identity is a primary attack surface in healthcare. Attackers abuse weak MFA, shared accounts, excessive privileges, service accounts and insufficiently controlled external access. With many user groups, temporary staff and supply-chain partners, one account can provide access to multiple critical systems.
Web applications, patient portals, appointment platforms and triage solutions process sensitive data and often integrate with underlying healthcare systems. Vulnerabilities such as broken access control, IDOR, weak session security and insufficient input validation can give unauthorised access to patient data or internal functions.
Medical devices, building management, laboratory equipment and network-connected diagnostics often have long lifecycles and are difficult to patch. Attackers look for weak segmentation, default passwords, management interfaces and outdated protocols. The main risk sits in the connection between IT and medical technology.
Healthcare organisations increasingly use cloud and SaaS for collaboration, data processing, EHR functionality and supply-chain exchange. Risks arise from misconfigured tenants, public storage, excessive privileges, weak logging and insecure integrations. One cloud error can expose medical data at scale.
Healthcare organisations depend heavily on software suppliers, technology partners, managed service providers and regional collaborations. Attackers abuse these trust relationships: remote administration, VPN access, shared accounts, weak monitoring and overly broad access to management portals.
In healthcare environments, the greatest risk often lies in the connection between systems. A vulnerable patient portal can provide access to an internal API. An unnecessarily reachable management system can enable lateral movement. A service account with excessive privileges can provide access to medical data. DeepBlue therefore looks not only at individual vulnerabilities, but at the path an attacker can follow from initial access to privilege escalation, data access, process disruption and potential impact on critical healthcare systems.
These attack paths show where technical measures are immediately required and where structural improvement is necessary. Examples include stronger segmentation between healthcare systems and office automation, tighter privileges on identity and service accounts, hardening of external access, restriction of management interfaces and improved logging and detection. DeepBlue translates findings into technical detail, remediation priorities and practical measures. This creates one clear view for executives, security, IT operations and those responsible for care continuity.
Yes. Continuity of care comes first. We agree scope, timing and test intensity in advance, perform higher-risk actions in consultation or outside peak hours, and work on an acceptance environment where needed. Our senior specialists decide at every step what is responsible, rather than letting a tool run unchecked.
We do not need access to medical content to demonstrate attack paths. Where we unavoidably touch data, we limit ourselves to the minimum evidence and record nothing unnecessarily. The focus is on demonstrable impact, not on viewing records.
Yes. We look precisely at the point where IT and medical technology meet, because that is where weak segmentation, default passwords and unpatched legacy often sit. For vulnerable equipment or systems that cannot be interrupted, we choose an approach that does not endanger operation, for example observational testing or a test unit.
Our reporting is structured so you can use the results directly as evidence towards these frameworks. We test the controls that matter and translate findings into concrete risks, so a test contributes to demonstrable compliance rather than remaining an isolated snapshot.
The EHR supplier is responsible for the security of its own system. We test the integration and connections with the EHR, such as administrative access and supplier VPNs. That external access is a recurring risk in healthcare.
At least annually, and additionally after major changes such as a new patient portal, a cloud migration or a connection with a new supplier. Continuity between tests is best safeguarded with monitoring, for which our Managed SOC is a logical addition.
Awareness and skills determine how well staff recognise and respond to threats. DeepBlue delivers phishing simulations, awareness training and technical exercises for SOC and IT teams. The content aligns with your processes, roles and realistic attack scenarios.
Red teaming is relevant for organisations that want to test their detection, response and resilience against realistic attack paths. The focus is on goal-driven scenarios, such as access to sensitive data, lateral movement towards business-critical systems or evasion of detection.
A Managed SOC supports organisations with continuous detection, triage and follow-up. Its value lies in use cases that reflect real attack paths, such as identity abuse, suspicious access to sensitive data, lateral movement and anomalous behaviour in cloud environments.
Speed is critical during incidents. DeepBlue investigates how an attacker gained access, which systems were affected, which data may have been accessed and which measures are needed to restore operations safely.
CISO as a Service supports organisations with security strategy, risk steering, supplier control, incident preparation and technical prioritisation. The focus is on actionable measures that fit your processes and available capacity.
Physical access can have digital impact. Consider workstations, reception desks, network ports, offices, server rooms and supplier zones. Physical security testing shows where physical security, human behaviour and cyber risk meet.
