Happy to announce the launch of the Alice in Supply Chains #podcast, posted monthly, focusing on topical discussions on the top news relevant to Third-Party Cyber Risk Management.

"Plant a tree, have a child, and write a book. These all live on after us, insuring a measure of immortality." We all know that these days, the writing a book part would probably be replaced with "host a podcast".

Given that inevitability, I have finally decided to face my impostor syndrome and my non-native and accented English and give that a go. Standing on the shoulders of the collective effort we do at @TenchiSecurity@infosec.exchange on publishing high-quality content on Third-Party Cyber Risk Management in the Alice in Supply Chains newsletter, and counting on the vast experience and expertise of my good friend and co-host @sawaba@infosec.exchange .

Please check it out and let us know what you think, we are really at the beginning of the learning curve here and can use the feedback. Hope you like it!

Super happy about this milestone on the @TenchiSecurity@infosec.exchange journey! We just raised a $7MM Series A from Bradesco PE&VC, L4 Venture Builder and Accenture.

The company was on a solid financial footing, and did not need to raise a round. But we decided to anyway once we found investor partners who saw the value in what we are doing and bring much more than "just" capital, and will help us strategically in executing our thesis.

The additional funding will allow us to accelerate product development, sales and marketing. Our goal? To be a proudly Brazilian global cyber security player, and disrupt the Third Party Cyber Risk Management space.

Huge thanks to all the customers, partners and team members who put their trust in us. Rest assured we will continue working hard to exceed your expectations.

Here at @TenchiSecurity@infosec.exchange our product is built on #AWS #serverless workloads, but we also use AWS #Batch to execute a few container-based tasks on #StepFunctions.

This blog post from Luis F. Pontes from our #DevOps team describes problems we encountered with inactive AWS Batch Job Definition revisions, due to a long known quirk in #CloudFormation. Plus, it presents a workaround we successfully implemented, with code examples.

Check it out at https://www.tenchisecurity.com/fixing-aws-step-function-errors-due-to-reference-to-inactive-aws-batch-job-definition-revisions/

Interesting statistics related to Third Party Cyber Risk Management on the World Economic Forum's Global Cybersecurity Outlook 2024 report.

54% of organizations have insufficient visibility of the vulnerabilities of their supply chains, including 64% of executives who believe their own organizations meet their minimum resilience requirements.

To me this clearly shows just how big of a blind spot #TPCRM still is for most companies. After all only companies that don't outsource any critical functions and don't give any third parties access to critical data could simultaenously believe that a) they meet their resilience requirements and b) they don't understand their third parties' vulnerabilities... and how many of those are out there? I have personally never bumped into any companies this vertically integrated, even in regulated markets.

The report also highlights the real impacts of neglecting this discipline. It claims 41% of companies that suffered a material impact from a cyberattack said it originated from a third party. This dovetails nicely from data we've seen elsewhere, including a figure that incidents originated at third parties were the leading source of cyber insurance claims in Q2 of last year.

You can read the full report here: https://www.weforum.org/publications/global-cybersecurity-outlook-2024/

This is why here at @TenchiSecurity@infosec.exchange we decided to tackle #TPCRM, which is gradually starting to get the visibility and prioritization it deserves. Get in touch if you want to learn more about how we are disrupting this market by going beyond risk reporting and focusing on risk reduction through a cooperative approach.

Had a wonderful time talking to Robert Martin from @mitrecorp@bird.makeup about their new Supply Chain Security framework System of Trust (https://sot.mitre.org/).

I truly believe this has the potential of catching on in a big way with the risk management and #TPRM #TPCRM community much the same way the ATT&CK framework caught on the security monitoring and testing folks, and for the same reasons.

TFW I realized I'll miss the @riskybusiness@infosec.exchange @riskybiz@infosec.exchange live podcast recording at RSAC because it is EXACTLY at the same time as I'm on stage presenting.

I mean, anything else I could have tried to move around. This is THE ONE THING I can't reschedule... 😢
