I See A Milestone, Not Just Another Funding Round

I’m delighted with the deal RedSeal just announced with STG.  I’ve worked in several start-ups — from the earliest stage, when the whole company could share a single elevator, all the way through acquisition by huge global corporations. My favorite times are when we’re all actively engaged with customers and the company has a sense […]

Warren Buffett’s Take On Cyber Insurance

Warren Buffett recently made clear how risk-averse his business is when it comes to cyber insurance. Addressing his annual shareholder meeting, he summarized the state of play like this: “I think anybody that tells you now they think they know in some actuarial way either what [the] general experience is like in the future, or what […]

Uber Hack: A Bad Breach, But A Worse Cover-Up

The Uber hack is a public lesson that a breach may be bad, but a cover-up is worse.  (See Nixon, Richard.)  It was a foolish mistake to try to hide an attack of this scale, but then, the history of security is a process where we all slowly learn from foolish mistakes.  We live in […]

Keep Up with the Basics

I just came across a WSJ Pro article titled “Inside the NSA: Companies Need to Follow the Basics,” and figured I could offer an “amen.” The NSA gets points for seeing things clearly – but then, I suppose that is their job, whether we like it or not! The area they discuss isn’t easy to write […]

The Internet of Things That Can Attack You

FORBES | February 17, 2017

By Dr. Mike Lloyd, RedSeal CTO

The Internet of Things crashed into the old Internet on Oct 21st, and it wasn’t pretty. A specialized but fairly simple bit of malware known as Mirai was used to cause huge numbers of simple Internet-connected devices (cameras, home routers, baby monitors, etc.) to […]

The Bleed Goes On

Some people are surprised that Heartbleed is still out there, 3 years on, as you can read here. What this illustrates is two important truths of security, depending on whether you see the glass half full or half empty.

One perspective is that, once again, we know what to do, but failed to do it.  Heartbleed is […]

Micro-Segmentation: Good or bad?

COMPUTING | 27 September 2016

Mike Lloyd, CTO at RedSeal, argues that more granular control is a good thing, but it’s easier said than done.

There’s a lot going on in virtual data centres. In security, we’re hearing many variations of the term “micro-segmentation”. (It originated from VMware, but has been adopted by other players, […]

Micro-Segmentation: Good or Bad?

There’s a lot going on in virtual data centers. In security, we’re hearing many variations of the term “micro-segmentation.” (It originated from VMWare, but has been adopted by other players, some of them adding top-spin or over-spin.)

We know what segmentation is. Every enterprise network practices segmentation between outside and inside, at least. Most aim […]

Hol(e)y Routers, Batman!

Most people think about network infrastructure about as much as they think about plumbing – which is to say, not at all, until something really unfortunate happens. That’s what puts the “infra” in the infrastructure – we want it out of sight, out of mind, and ideally mostly below ground. We pay more attention to […]
