  • If you missed it, Andy Sauer and Richard Wakeman broke down what can realistically be achieved in the time remaining and what to focus on now.  Catch the recap on CMMC Level-2 being the expectation, the timeline tightening and the gap between progress and readiness becoming clearer. 👇 Watch here: https://lnkd.in/eqkrV2EP #CMMC #DIB #Cybersecurity #NIST800171

  • Do or do not. There is no try.   Implemented, a control is: or it is not.   Documented, many things are: operating, they are not.   “Trying” to secure, many claim: under assessment… hold, it will not.   Known, your assets must be: aligned, your identity is, in use, your logging runs.   Reacting, enough it is not: built to hold, your environment must be.   Pass, you will: “trying”… you will not. That is the way.   May the 4th be with you. 💙 #CMMC #CMMCLevel2 #NIST800171 #DFARS #DIB #DefenseIndustrialBase #GovCon #Cybersecurity #CyberCompliance #OperationalCyber #MayThe4thBeWithYou

  • Day 30 of #Ones2Watch is Sentinel Blue 💙 Over the past month, we’ve highlighted companies shaping how cyber, intelligence, software, space, and emerging technologies are evolving across the Defense Industrial Base, within a landscape increasingly influenced by geopolitical pressure. Each is pushing the ecosystem forward. Working alongside the DIB, we see what that progress demands from the environment itself. More systems. More connectivity. More identity paths. More data moving across systems that were never designed to operate as one. That complexity shows up fast in how systems are accessed, how data moves, and how activity has to be understood in real time. That is where Sentinel Blue operates, ensuring controls reflect how systems are actually used, identity tracks how access really happens, and detection and response keep pace with how activity moves across the environment. 💡 Why we rock: We’ve built a managed cybersecurity program aligned to the NIST CSF and CMMC, designed to operate the way these environments actually function. It brings governance, security operations, and compliance into a single, holistic and comprehensive model, where controls are implemented in context and tied to how the environment is used. This approach creates continuous visibility across the environment, with monitoring, control, and response operating together as part of daily execution, like an orchestra. ⚙️ What sets us apart: As a Microsoft AOSG partner and one of the few MSPs and MSSPs with the credentialed authority of a C3PAO, we carry accountability that extends beyond implementation into assessment. Serving the DIB means closing the gap between what is written and what is running. That shows up in environments where controls live in the configuration, identity reflects real access, and monitoring follows how activity moves across endpoints, cloud, and users. In a landscape shaped by distributed systems, emerging technologies, and geopolitical pressure, the expectation is to deliver exactly what we say we will, and more. We prepare our clients for the future by building environments that can withstand both current and emerging threats. At the same time, we stay engaged with industry and government to advocate for secure approaches that benefit everyone. We close out #Ones2Watch by holding ourselves to the same standard we seek in others, continuing to rise and always setting the bar higher. As you’ve followed our Spring Edit picks, take a closer look at us. This is where it all comes together. #One2Watch.💙 #Ones2Watch #DefenseTech #DIB #SpaceTech #EmergingTech #Geopolitics #CMMC #CyberSecurity #MissionExecution #ZeroTrust #NIST #NationalSecurity

  • Day 29 of #Ones2Watch is Picogrid ⚡ We keep adding systems across the Defense Industrial Base. Sensors, platforms, autonomy, edge devices. Each one does its job. Few speak the same language. So teams end up stitching data across systems that were never designed to connect, in environments where time and clarity are critical. Enter Picogrid. They are creating the connective layer that allows systems, sensors, and software to operate together at the edge, turning fragmented inputs into something coherent, usable, and immediate. 💡 Why they rock: Picogrid treats integration as infrastructure. They connect disparate systems and data sources in real time, enabling interoperability across environments that were never designed to work together. What once required custom integration, manual workarounds, and time becomes part of the system itself. That shift allows systems to operate as one, where coordination becomes native to the environment. ⚙️ What sets them apart: Picogrid removes the need to rebuild integration for every new system, enabling systems to connect and operate as one from the start across distributed and constrained environments. Most of the delay in these environments shows up at the seams between systems. Picogrid eliminates that friction by allowing systems to connect where they already are, so integration does not become the work. The result is an environment that adapts as new capabilities come online, where coordination is built in and decisions are made on complete, aligned context. In a world where systems are constantly added, updated, and expected to work together in real time, advantage is shaped by how quickly they can connect, share, and act as one. Across the DIB, Picogrid is pushing directly on that, in a way that reflects how modern, distributed operations need to function. We like it, want to see more of it, and that is why they're today’s #One2Watch 💙 #Ones2Watch #DefenseTech #DIB #EdgeComputing #Interoperability #MissionExecution #Autonomy #DataIntegration #NationalSecurity

  • Day 28 of #Ones2Watch is Rebellion Industries We are generating more data across the Defense Industrial Base than decisions can keep up with. Across every mission set, inputs are expanding. Sensors, feeds, telemetry, reporting. The expectation is faster decisions with more context, but the systems feeding those decisions were never designed to operate as one. So operators are left to assemble meaning under pressure, in real time. That is an operational constraint. Rebellion Defense leans directly into it by building software that connects data, models, and operators in real time, so decisions are shaped as they are made. 💡 Why they rock: Rebellion is engineering the decision layer itself. They place AI inside the operational loop, where data is fused, models are applied, and outputs arrive at the exact moment a decision is required.  That shifts the role of AI from explaining to driving. And in defense environments, that distinction is everything, because decisions are made under pressure, with incomplete context, and the cost of delay or misinterpretation is operational failure. ⚙️ What sets them apart: What stands out is the level of control and intent in how they’ve built this. Rebellion constructs a tightly integrated system where ingestion, model execution, and operator interaction are designed together, so outputs arrive with context, timing, and relevance tied directly to the decision at hand. This creates a decision environment where information is immediately usable, workflows are aligned to action, and the path from signal to decision is compressed into something operators can rely on. From where we sit, this matters more than it gets credit for. Advantage across the DIB is defined by how quickly and confidently information turns into action. Rebellion is pushing directly on that and doing it in a way that reflects how modern defense operates. We're a fan and looking forward to what they do next, and that's why they're today’s #One2Watch 💙 #Ones2Watch #DefenseTech #DIB #MissionExecution #ArtificialIntelligence #DecisionAdvantage #DataToAction #NationalSecurity

  • 🎙️ Now Live on The Watchers We still tend to frame cybersecurity as a technical problem, but it is playing out somewhere else entirely right now in how countries support each other, how policy moves, and whether operations can actually hold under pressure. Andy Sauer sits down with Mary B. to talk through what is happening with U.S. cyber assistance, digital trust, and supply chains that don’t stop at borders. When those start to move at the same time, the impact is not theoretical. It lands on real environments, real partners, and real decisions that have to be made quickly. They get into leadership gaps, uneven policy signals, and the tension between sovereign AI ambitions and infrastructure that is already deeply interconnected. 💙 Worth the listen for sure, so tune in! 👉 Watch the full episode: https://lnkd.in/et9D6EPf #TheWatchers #CyberSecurity #NationalSecurity #SupplyChainSecurity #DigitalTrust #Geopolitics #DefenseIndustrialBase #CyberStrategy

  • Day 27 of #Ones2Watch is Second Front 🚀 There’s a quiet bottleneck in the Defense Industrial Base that doesn’t get talked about enough. It’s not innovation or capability. We can build at commercial speed, but deployment into government environments isn't a speedy thing. IL levels, accreditation paths, and compliance boundaries slow that momentum to a crawl. What should be an advantage becomes delay, and delay compounds. Second Front focuses on the delivery layer, operationalizing how software moves into DoD environments with security, compliance, and speed intact, and is working to improve the speed factor. 💡 Why they rock: Second Front sits between innovation and mission execution and treats it like an engineering problem. Their platform handles the complexity of IL compliance, continuous authorization, and secure delivery across DoD environments, so teams are not rebuilding at every boundary. Their platform handles IL compliance, continuous authorization, and secure delivery across DoD environments, eliminating the need to rebuild at every boundary and making deployment repeatable. ⚙️ What sets them apart: It's how deliberate they are about the last mile and how technical the approach is. They have built a structured delivery layer that abstracts DoD complexity, embedding compliance controls, configuration, and accreditation alignment directly into the pipeline so software can move across IL boundaries without being re-engineered each time. That shifts deployment from a manual, program specific effort into something repeatable and scalable, where authorization and delivery operate as part of the system rather than external gates. From where we sit, this carries more weight than most realize. In the DIB, advantage is how quickly and reliably capability is put to use. Second Front is shaping that reality in a way that aligns with how modern defense needs to operate, and that is why they are today’s #One2Watch 💙 👉Learn more about Second Front Systems: https://lnkd.in/dFFuNdqy #Ones2Watch #DefenseTech #DIB #DoD #MissionExecution #DevSecOps #CloudSecurity #CyberSecurity
