About Asimily

Asimily sells inventory and prioritized risk mitigation insights for every IoT, OT and IoMT device. Asimily shows every discovered device, maps out the attack surface, and prioritizes and scores the riskiest devices. Asimily says the result is an answer on what is on the network, attack paths and which devices matter most, refreshed continuously instead of on an ad-hoc basis.[4][10]

Asimily identifies devices based on their network traffic. Asimily finds and classifies each device into a family, along with all apps, services and connections. Asimily gathers device information using passive-only or passive and active methods, depending on the monitored environment. Asimily protects devices during data gathering using passive, protocol-based or API-based methods.[10][14]

Asimily says it auto-generates, simulates, evaluates and applies validated segmentation policies that are specific to a customer's network. Asimily says these segmentation policies minimize the blast radius, eliminate attack paths and are proven safe through simulation before they go live. Continuous Segmentation keeps enforcement matched to the network as devices are patched, moved, or retired. Asimily continuously monitors policies to ensure effectiveness and can simulate segmentation scenarios to understand the impact of the policies being applied. Asimily says policies stay aligned as the network changes when devices are moved or added, when a vulnerability is discovered or when business requirements change.[1][4][7][10]

Asimily evaluates each new vulnerability and customizes the risk level for each individual device, considering the vulnerability, importance, network, and configuration factors. Risk Simulator shows the Risk ROI for any given action. Asimily gives a risk score from 0-100. Risk Mitigation draws on Asimily Labs' ATT&CK Analysis to guide the choice of patch, mitigation or segmentation against attack paths. Asimily says it uses patented AI/ML techniques to analyze each vulnerability to learn how to stop the exploit that uses it. Asimily describes segmentation rules orchestrated through existing NACs and firewalls.[10][15][16]

Asimily normalizes the firmware update process across IoT manufacturers so it looks the same to device fleet operators.[17]

Threat and Response monitors for anomalous IoT, OT and IoMT behavior and can launch protective actions from alerts to quarantining. Asimily says it detects threats using 100+ sources including EPSS and KEV. Asimily can send alerts or automatically quarantine anomalous devices. Asimily offers packet capture for any monitored device. Asimily provides a single place to block services or ports, quarantine devices or segment compromised devices away from other assets. Asimily provides a software platform to aid the incident response process.[4][18]

Asimily says laws and security frameworks, some of them HIPAA, NIST and CIS, explicitly demand security for IoT, OT and IoMT devices. Configuration Control documents a device's safest states to speed recovery from errors and ransomware. Configuration Control takes a snapshot of a device's hardened state, including network neighbors. Asimily detects drift in device configurations and offers device timelines to detect causes.[8][19]

Asimily says it provides tools to identify and address IoT vulnerabilities in healthcare, ensuring the protection of patient data without interrupting the delivery of critical care. Asimily says that by securing IoT devices, manufacturers can safeguard their intellectual property, prevent production disruptions, and maintain the trust of their customers and partners. Asimily equips government entities worldwide with tools to secure their IoT devices, protect critical infrastructure, and ensure data privacy. Asimily describes protection for educational institutions that depend on interconnected devices for learning, research and campus operations.[6][10]

Asimily describes a manufacturer that needed compliance with CMMC and NIST 800-171 as a federal contractor. Asimily describes a large manufacturer with multiple distinct locations that estimates downtime at about $1 million per hour. In that customer example, Asimily mini Edge processors, which are small form-factor devices, reduced hardware deployment costs from over $100,000 to roughly $15,000. For one manufacturer, Asimily developed a custom, low-overhead software collector script designed to interface with the manufacturer's OPC architecture.[1][2][4][5][6][7][8][9][10][11][15][17]
