Zero Trust

We’ve spent the last decade building zero trust architectures. Device posture checks, tiered application access, network segmentation, conditional access policies. All designed around a core principle: don’t implicitly trust anything, verify everything, and limit the blast radius when something goes wrong. AI tools are quietly undoing a lot of that work. We’re connecting AI tools to everything, and we’re making them controllable from anywhere. That combination is a fundamental challenge to how we’ve been thinking about defense in depth....

Everyone’s shipping AI agents right now. Connect your agent to Slack, let it read your email, have it make PRs on your behalf. This can be via MCP, no-code AI tools like n8n or direct via APIs. However, we’re in this awkward middle ground where the tooling to use agents is miles ahead of the tooling to secure them. The fundamental problem isn’t new, it’s the same challenge we’ve had with any system that acts on behalf of a user, but agents amplify it in ways that existing access control patterns weren’t built for....

Over the past few weeks, my feed has been filled with a juxtaposition: security people warning about the risks of AI browsers and SF tech bros saying they have 10x’d their performance by using an AI browser to order lunch from DoorDash. A lot of people are crying about prompt injection, but that isn’t the only risk posed by AI browsers. The guidance seems to be very much “just block them” at this stage, and while that’s a pragmatic short-term solution, I don’t think it’ll work for very long....

Business Process Outsourcing (BPO) is when you hire a group of contractors from a single company to complete long-term work for you. This is typically something like customer support, where you want to outsource first-line tech support to a cheaper region or get more coverage in a timezone where you don’t have an existing presence. The problem is that zero trust architecture requires every employee accessing your critical SaaS applications to come from a managed device....

Enterprise AI search tools are a simple concept. They take in all of the data from all of your productivity tools and give you a single pane of glass to search across your company’s entire corpus. This lets you search across all of the documents, email and chat regardless of what tool they are stored in. The productivity benefits are apparent here because who hasn’t spent half an hour searching for that doc you made three years ago?...

I’m a big fan of building security into existing processes, a term coined as “secure paved roads” by Jason Chan, Ex-Netflix CISO. The idea behind this is that security should mostly be invisible. The average employee should simply not have to think about high-consequence security domains. They’ll use tools that make their life easier, and that tooling has security built in by default. Yes, they can divert from that paved path, but they’ll generally have a worse experience....

Background Third-party risk management (TPRM) has its challenges. It is a relatively new area that has been developing rapidly, but many programs face significant issues as their companies grow. TPRM rarely scales linearly with the business or the number of applications in use. There are no easy fixes, but you can make steady improvements. I will share some practices I have used to improve programs over time, which you can take away and adapt to your situation....

Summary In this blog post, I’ll go into the basics of third-party risk management, what the challenges are, and give you an overview of what an average Third-Party Risk Management (TPRM) program looks like. This is designed primarily for people new to the industry up to the mid-level, but there might be a few points valid for seniors with mature programs too. Background In recent years TPRM has become a growing chunk of work for cyber security teams....

I’ve seen a lot of zero trust setups, from off-the-shelf vendor tools to complex custom-built solutions. I’ve found that many of them share the same problems and below I’ve listed the most common 8 I see. These usually stem from the design phase so the earlier you catch them the better! Admittedly some are those gnarly enterprise security problems which require a culture change and effort shift, especially number 8 as increasing manual workloads is not usually the top priority....

Introduction I’ve seen a few blog posts lately about building corporate security but they are always… well.. so corporate. They are always viewed through the lens of extreme risk but the reality is that most places are not banks or government agencies. The examples given often lock things down to the point where manual work is required for every request which is unrealistic in most public companies. You can (and should) try to achieve your security goals while impacting your employee experience as little as possible in the process....
