For too long, cybersecurity in the Cyber-Physical Systems (CPS) world has been conducted in the dark: vendors promising “visibility,” hiding their prices, and leaving customers with partial answers and growing risks.
At Phosphorus, we’ve seen this story play out too many times. Security leaders buy expensive tools that cost more than they expected, take longer to deploy than they wanted, and promise clarity, only to discover that they’re still operating in the dark. Their security issues remain unresolved.
That’s why we’re declaring independence. Independence from opaque pricing, from passive tools, and from a mindset that treats visibility as a luxury.
We believe security should never be a mystery sold at a premium. So, we’ve done something about it.
Bringing Devices and Pricing Out of the Dark
Phosphorus has introduced the industry’s first fully transparent, per-device pricing model for xIoT security and management.
Why? Because our customers deserve to know exactly what they’re getting and exactly what it costs.
No hidden fees. No surprise, extra costly hardware requirements. No long deployment timelines. Just clear pricing, real results, and faster protection.
For $5 per device per year, our Intelligent Active Discovery gives instant visibility and risk assessment into every connected device—IoT, OT, IoMT, industrial, medical, you name it. Large organizations can even unlock unlimited discovery through qualifying platform purchases, achieving total visibility from day one.
From there, customers can choose modular capabilities like password management, firmware management, certificate management, device drift monitoring & response, device log retrieval, and device backups, each priced between $5 and $10 per device annually. Pay for only what you need. Expand when you’re ready. We’ve built the platform with automation that puts you in complete control. Now we’ve built our pricing model to do the same.
“We’re flipping the script—making pricing and protection equally transparent and accessible. Security shouldn’t be a mystery sold at a premium. Customers deserve proof, not promises”
– Sonu Shankar,
President & COO
Visibility Should Be a Right, Not a Luxury
In today’s enterprise, connected devices are everywhere, and growing fast. From IP cameras and printers to patient monitors, HVAC controllers, and smart sensors, the diversity and scale of these assets are staggering.
And yet, most organizations don’t even know what’s connected to their networks.
That’s because legacy “visibility-only” tools weren’t built for this reality. They rely on expensive hardware, complex SPAN and TAP setups, and deployment cycles that take months or years. They offer partial visibility, outdated data, and no path to remediation.
At Phosphorus, visibility is a security right. We built our platform to deliver it—fast, safely, and with precision.
Our Intelligent Active Discovery deploys in hours, not months. It scans a representative Class B network in 15 minutes, without the need for SPAN ports, packet brokers, or proprietary hardware, and delivers deep, accurate device intelligence and risk assessment. After scanning over 6.3 billion IP addresses, we’ve seen what others miss: the unmanaged, unseen devices that represent organizations’ largest attack surface.
From Observation to Action: Turning Visibility Into Security
Seeing your devices is just the beginning. Fixing them is where real security happens.
Legacy discovery tools stop at observation. They show you problems but don’t solve them. Phosphorus takes the next step with autonomous remediation.
Legacy discovery tools stop at observation. They show you problems but don’t solve them. Phosphorus takes the next step with autonomous remediation.
Our platform doesn’t just identify vulnerable devices; it puts you in control to secure them automatically with the flexibility and granularity required to do so safely.
- Password Management: automatically rotates and enforces secure device credentials across IoT, OT, and industrial assets.
- Firmware Management: upgrade and downgrade device firmware at scale to eliminate known vulnerabilities before they can be exploited with the context of CVEs, KEV, and EPSS.
- Certificate Management: issues, rotates, and validates digital certificates so device connections can be trusted.
- Device Drift Monitoring & Response: detects configuration drift or policy violations and restores devices to a compliant state.
- Device Backups: ensures operational and ransomware resilience by maintaining secure device backups for rapid restoration and continuity.
- Device Log Retrieval: centralizes log collection and analytics for detailed device-level forensics and compliance verification.
All of it happens safely, automatically, and continuously, with human oversight, not limitations.
It’s the first truly autonomous remediation framework for xIoT, transforming visibility into measurable protection.
As Phillip Taylor, Principal at YSN Co. and former Siemens Industrial Networks Specialist, told us:
“Phosphorus combines full-spectrum visibility with active remediation—something we’ve waited decades to see in OT cybersecurity. It’s the first platform that actually lets engineers fix the problems they discover, safely and at scale.”
Proof That Simplicity Wins
Transparency doesn’t just feel better—it works better.
Phosphorus is proving that enterprises are ready for clarity and action, not complexity and excuses. We’ve seen a 157% increase in password rotations and a 65% increase in firmware updates year-over-year. Those numbers tell a powerful story: when visibility is easy and remediation is automatic, organizations take control of their security posture and win.
Because security doesn’t come from watching. It comes from doing.
Comply, Connect, and Protect
The world’s critical infrastructure is embracing Comply-to-Connect standards, ensuring that only trusted, secure devices ever reach the network. Phosphorus enforces this automatically, identifying and validating every device before it connects.
We also protect organizations from banned or restricted hardware, including devices prohibited under NDAA Section 889, even when they’re unmarked or white-labeled.
“Finding a device is step one,” says Shankar. “Ensuring it’s safe, compliant, and trusted is what matters. We’ve found unapproved equipment on critical systems that should never have been there—and when that happens, it’s not just a compliance issue, it’s a compromise waiting to happen.”
The Future Is Transparent
Phosphorus was built to change the relationship between enterprises and their devices, to make xIoT security accessible, actionable, and autonomous.
We’re done with opaque pricing. We’re done with passive tools. And we’re done with the idea that visibility is enough.
We’re here to make security transparent, measurable, and real.
With Phosphorus, organizations can finally see every device, understand every risk, and fix every problem, safely, automatically, and at scale.
