A connected medical device and IoT security program assesses existing security practices, identifies security shortcomings, and puts necessary protocols in place to minimize the risk of these devices.
A team of healthcare cybersecurity professionals should start by identifying each IoT/IoMT device in your organization’s network, ensuring that they are fitted with proper security controls and follow the organization’s standards.
IoMT devices have become critical in providing effective patient care and achieving desired patient outcomes. If they aren’t sufficiently protected, patients’ lives can be put at risk. By proactively managing threats and vulnerabilities, healthcare organizations can ensure the reliable and safe use of medical devices, ultimately supporting better healthcare delivery and innovation.
Key benefits of IoMT:
- Patient safety
- Data privacy
- Operational reliability
- Regulatory compliance
- Trust and reputation
Managed phishing
Phishing is one of the top methods cybercriminals use to gain access to healthcare networks and data, yet over one-third of health IT employees never perform simulated phishing tests.
Coupled with a lack of employee training, this risk leaves healthcare organizations vulnerable.
Fortunately, SOC services like managed phishing and employee education can help organizations gain awareness and take this threat seriously.
During controlled organized phishing simulation, employees learn to spot and report phishing emails, strengthening the organization’s cybersecurity posture.
Key benefits of managed phishing:
- Increased employee awareness
- Risk reduction
- Behavioral insights
- Compliance support
- Proactive defense
Endpoint detection and response
Effective (EDR) involves identifying sophisticated attacks, tracking their movements, and remediating security threats.
EDR enhances an organization’s cybersecurity posture by providing advanced threat detection, rapid incident response, comprehensive visibility, proactive threat hunting, detailed forensics, and reduced dwell time.
These capabilities also provide detailed logs and records of endpoint activities, which are crucial for forensic analysis and understanding the attack vector and impact, and helping organizations protect their endpoints from increasingly sophisticated cyber threats.
EDR systems are designed to detect a wide range of suspicious activities and security threats on endpoints. Cybersecurity professionals can then track the data on a live dashboard and address security issues quickly. For example, this process might involve identifying:
- File-based malware
- Fileless malware
- Ransomware
- Unusual process execution
- Process injection
- Credential dumping
- Lateral movement
- Privilege escalation
- Persistence mechanisms
- Multi-staged attacks
In order for all the tools, processes, and people to work together, having a team of healthcare cybersecurity professionals leading the way is vital.
This proactive approach allows organizations to identify and respond to threats quickly, minimizing potential damage and enhancing overall security posture.
Through these services, you can identify and control risks to stay ahead of cyberattacks.
Key benefits of EDR:
- Real-time threat detection
- Rapid incident response
- Advanced threat hunting
- Comprehensive visibility
- Automated remediation
Dark web monitoring
Dark web monitoring is a critical cybersecurity practice involving the continuous surveillance of dark web forums, marketplaces, and other hidden services to identify and mitigate potential threats to an organization.
By actively monitoring the dark web, security teams can detect compromised data, such as stolen credentials, personal information, intellectual property, and confidential business documents that may be for sale or exposed.
This proactive approach allows organizations to respond swiftly to data breaches, inform affected individuals, and take necessary actions to prevent further exploitation.
Additionally, dark web monitoring helps identify emerging threat trends, enabling organizations to bolster their security posture and stay ahead of cybercriminal activities.
Overall, dark web monitoring is essential for comprehensive threat intelligence and maintaining the integrity and confidentiality of sensitive information.

Covering what traditional security models may miss
Cyber threats don’t adhere to office hours. A continuous SOC, operational 24/7/365, is essential for detecting and responding to threats promptly, mitigating potential data breaches, and minimizing downtime.
Security personnel may not be effectively utilized if their skills and capabilities are confined to a traditional nine to five schedule, as this reduces overall efficiency of any data security measures a healthcare organization puts in place.
Mid-sized healthcare organizations often struggle with limited resources, including budget constraints and a shortage of cybersecurity expertise. As a result, they don’t invest appropriately in 24/7 security coverage.
Unfortunately, this leaves healthcare organizations vulnerable to threats outside of these timeframes.
Other significant risks in under-investing in security include:
- Limited coverage
- Higher breach risks
- Compliance issues
- Reduced threat intelligence utilization
These risks and consequences of under-investing in data security can also impact business continuity, create competitive disadvantages, and lead to inefficiencies and stress within the security team.
The cost of a data breach far exceeds the investment required for proactive cybersecurity measures, making it imperative for organizations to allocate adequate resources to security initiatives.
