The Fastest Way to Reduce Risk

Risk remediation is a massive challenge for this manufacturer, whose high-end equipment (CNC machines, controls, and machining centers) and core OT devices (PLCs, SCADA controllers, distributed I/O systems) largely run on legacy operating systems. Because of strict OEM warranties, lack of available patches, and the inherent fragility of these systems, traditional active scanning is disruptive and patching is often operationally impossible. Asimily competitors simply output long lists of theoretical vulnerabilities, telling the manufacturer to replace everything, which was operationally impossible. They needed to non-disruptively map their on-premises network topologies, using passive asset discovery via SPAN or ERSPAN port mirroring, to understand actual attack paths and prioritize remediation that rapidly removes the most risk.

• Identify which devices truly have a viable attack path.
• Prioritize risk remediation based on real-world impacts (safety, regulatory, cost, and downtime).
• Ensure compliance with stringent cybersecurity standards (including CMMC and NIST 800-171) to maintain security clearance as a federal contractor with audit-ready data.

Operating multiple distinct locations, this large manufacturer faces catastrophic consequences if production halts, with downtime costing an estimated $1 million per hour. Their highly distributed infrastructure made traditional security hardware deployments offered by Asimily competitors prohibitively expensive; placing standard $10,000 aggregation boxes at every necessary network juncture would have driven project costs into the hundreds of thousands of dollars. Furthermore, they needed to discover “child” devices sitting behind PLCs (often obscured by industrial NAT or backplane routing) without actively scanning and disrupting the fragile OT network.

• Gain complete visibility across all industrial devices across multiple spread-out facilities.
• Achieve complete device visibility safely, with zero operational impact or downtime.
• Keep hardware and deployment costs manageable across a highly distributed architecture.
• Prioritize risk intelligently using Asimily’s ATT&CK Analysis to speed remediation and focus on what improves security the most.

This manufacturer had a critical blind spot: they had zero visibility into the network of devices sitting deeply behind their PLCs within lower-level cell zones (Purdue Levels 0-2). Traditional methods like configuring SPAN sessions, installing physical TAPs, or placing low-end collector boxes were not physically or architecturally feasible. After piloting other well-known OT security vendors who relied strictly on passive wire data analysis at higher network layers, they found those vendors could not see behind the primary PLCs. The child devices were invisible during these pilots.

• Achieve 100% visibility into the child devices operating behind the PLCs.
• Extract deep device logs and behavioral data without disrupting standard OT communications, including Modbus TCP, PROFINET, and Ethernet/IP.
• Partner with a vendor with extensive engineering experience handling legacy devices, proprietary backplane routing, and complex industrial protocols.

Managing a massive, sprawling network that blends IoT, OT, and IT devices (including SCADA controllers, distributed I/O systems, and terminal operating systems), this municipal port needed comprehensive device querying. Passive-only scanning often missed dormant devices or struggled with asymmetric routing and encrypted payloads, while aggressive active scanning (typical of traditional IT vulnerability scanners) risked crashing the fragile TCP/IP stacks of critical port infrastructure. Additionally, the sheer scale of the environment meant they needed nearly 100 hardware collectors costing north of $10,000 each, which threatened to kill the project budget entirely.

• Achieve total, converged visibility across a highly complex, mixed IoT, OT, and IT port environment.
• Safely gather deep telemetry using a blend of active and passive techniques without causing network latency or device unresponsiveness.
• Drastically reduce the required hardware footprint and overall project cost.
• Ensure continuous, 24/7 port operations and supply chain logistics were not jeopardized.

While traditional OT security focuses heavily on industrial environments, this major bank faced a massive challenge with their Building Management Systems (BMS), including HVAC controllers, physical access systems, and elevators running protocols like BACnet and LonWorks, alongside a rapidly expanding fleet of corporate IoT devices (VoIP, smart displays, networked printers). They didn’t just have a visibility problem; they had a mitigation problem. Knowing a device was vulnerable wasn’t enough without a way to actively secure them. Competitors offered standard passive visibility but fell flat when tasked with actionable remediation, effectively leaving the bank’s security team with alert fatigue and no mechanism to actually push updates or mitigate the IoT risks.

• Discover and precisely classify a vast, distributed network of building OT and corporate IoT devices.
• Go beyond basic network visibility to actively mitigate vulnerabilities on critical IoT devices through orchestrated patch and lifecycle management.
• Select a vendor with a forward-leaning technical roadmap demonstrating competitive product capabilities for automated IoT lifecycle management.

This city manages highly dispersed infrastructure, ranging from IT networks to smart traffic cameras and critical wastewater SCADA systems. Because their network is so geographically spread out, relying purely on basic scanning (like SNMP walks) frequently failed to capture a significant portion of their traffic due to unsupported MIBs, disabled services, or firewall drops. They needed a vendor capable of deep, API-based querying to extract granular information from remote IoT devices that couldn’t be efficiently accessed by traditional, heavy hardware appliances.

• Gain deep visibility into distributed city infrastructure, even in areas where SPANning all traffic is impossible at low cost and complexity.
• Partner with a vendor that goes beyond mere visibility to offer true mitigation and segmentation for critical municipal OT (like wastewater management).
• Gain a contextual understanding of actual exploitability to inform intelligent, dynamic network segmentation that stays up to date with evolving threats.

This large healthcare organization with over 15 sites lacked the ability to quantify risk due to a lack of visibility into connected medical and IoT devices, in addition to their associated vulnerabilities. Without a remediation strategy, their medical device inventory was maintained by clinical engineering in a reactive manner. The organization needed a solution to manage and prioritize remediation efforts to more efficiently reduce risk and an easy way to communicate these efforts to their board.

• Gain full visibility into the connected medical and IoT device inventory with associated exploitable vulnerabilities.
• Develop a comprehensive ongoing security program.
• Prioritize remediation and streamline mitigation activities with the outsourced clinical engineering team.
• Communicate risk reduction, benchmarking, compliance, and NIST coverage to the board.
