Summary
In this episode, Andrey and Mattias deliver a security-heavy recap of AWS re:Invent 2025 announcements, while noting that Paulina is absent and wishing her a speedy recovery. Out of the 500+ releases surrounding re:Invent, they narrow the list down to roughly 20 features that security-conscious teams can act on today — covering encryption, access control, detection, backups, container security, and organization-wide guardrails. Along the way, Andrey reveals a new AI-powered product called Boris that watches the AWS release firehose so you don't have to.
Key Topics
AWS re:Invent Through a Security Lens
The hosts frame the episode as the DevSecOps Talks version of a re:Invent recap, complementing a FivexL webinar held the previous month. Despite the podcast's name covering development, security, and operations, the selected announcements lean heavily toward security. Andrey is upfront about it: if security is your thing, stay tuned; otherwise, manage your expectations.
At the FivexL webinar, attendees were asked to prioritize areas of interest across compute, security, and networking. AI dominated the conversation, and people were also curious about Amazon S3 Vectors — a new S3 storage class purpose-built for vector embeddings used in RAG (Retrieval-Augmented Generation) architectures that power LLM applications. It is cost-efficient but lacks hybrid search at this stage.
VPC Encryption and Post-Quantum Readiness
One of the first and most praised announcements is VPC Encryption Control for Amazon VPC, a pre-re:Invent release that lets teams audit and enforce encryption in transit within and across VPCs. The hosts highlight how painful it used to be to verify internal traffic encryption — typically requiring traffic mirroring, spinning up instances, and inspecting packets with tools like Wireshark. This feature offers two modes: monitor mode to audit encryption status via VPC flow logs, and enforce mode to block unencrypted resources from attaching to the VPC.
Mattias adds that compliance expectations are expanding. It used to be enough to encrypt traffic over public endpoints, but the bar is moving toward encryption everywhere, including inside the VPC. The hosts also call out a common pattern: offloading SSL at the load balancer and leaving traffic to targets unencrypted. VPC encryption control helps catch exactly this kind of blind spot.
The discussion then shifts to post-quantum cryptography (PQC) support rolling out across AWS services including S3, ALB, NLB, AWS Private CA, KMS, ACM, and Secrets Manager. AWS now supports ML-KEM (Module Lattice-Based Key Encapsulation Mechanism), a NIST-standardized post-quantum algorithm, along with ML-DSA (Module Lattice-Based Digital Signature Algorithm) for Private CA certificates.
The rationale: state-level actors are already recording encrypted traffic today in a "harvest now, decrypt later" strategy, betting that future quantum computers will crack current encryption. Andrey notes that operational quantum computing feels closer than ever, making it worthwhile to enable post-quantum protections now — especially for sensitive data traversing public networks.
S3 Security Controls and Access Management
Several S3-related updates stand out. Attribute-Based Access Control (ABAC) for S3 allows access decisions based on resource tags rather than only enumerating specific actions in policies. This is a powerful way to scope permissi
