Find your customers on Roku this Black Friday

As with any digital ad campaign, the important thing is to reach streaming audiences who will convert. To that end, Roku’s self-service Ads Manager stands ready with powerful segmentation and targeting options. After all, you know your customers, and we know our streaming audience.

Worried it’s too late to spin up new Black Friday creative? With Roku Ads Manager, you can easily import and augment existing creative assets from your social channels. We also have AI-assisted upscaling, so every ad is primed for CTV.

Once you’ve done this, then you can easily set up A/B tests to flight different creative variants and Black Friday offers. If you’re a Shopify brand, you can even run shoppable ads directly on-screen so viewers can purchase with just a click of their Roku remote.

Bonus: we’re gifting you $5K in ad credits when you spend your first $5K on Roku Ads Manager. Just sign up and use code GET5K. Terms apply.

Hello, Visionary CTOs! 🌟

This week, we’ll talk about the growing challenge of AI agents working together—and how the lack of unified communication protocols like MCP, A2A, and ACP is slowing real progress.

As agents become more autonomous, seamless coordination isn’t optional—it’s the next big hurdle for scalable, intelligent systems.

🛡️ SonicWall Zero-Day Under Fire: Akira Ransomware Exploits SSL VPN Flaw

Security researchers report a surge in ransomware attacks, notably targeting SonicWall Gen 7 firewalls via the SSL VPN feature—suggesting exploitation of a previously unknown zero-day vulnerability, even on fully patched devices.

Key Takeaways:

  • 🔍 Zero-Day Exploitation Detected: Akira ransomware is actively exploiting an apparent zero-day vulnerability, enabling unauthorized access via SonicWall SSL VPNs—even on up-to-date firewalls.

  • ⚠️ SSL VPN Feature at Risk: Targeted incidents primarily involve Gen 7 TZ and NSa-series devices with SSL VPN enabled, prompting advisories to disable this feature temporarily.

  • 🛠️ Mitigation Guide Issued: Admins are urged to disable SSL VPN, enforce MFA, restrict VPN access to trusted IPs, remove inactive accounts, and enhance botnet/geolocation protections.

  • ⏱️ Rapid Attack Timeline: Threat actors swiftly escalate from VPN compromise to domain control or ransomware deployment—often within hours—underlining urgency in response.

🧠 The Problem With AI Agent-to-Agent Communication Protocols

The explosion of competing standards—from A2A to MCP to ACP—is turning a once-simple challenge into a fragmented barrier, limiting scalability, interoperability, and collaboration among intelligent agents.

Key Takeaways:

  • ⚠️ Protocol Proliferation Stalls Progress: Dozens of overlapping standards threaten to create a fractured agent ecosystem, undermining interoperability.

  • 🔄 Integration Complexity Is Rising: Combining protocols like A2A and MCP exposes semantic mismatches, security gaps, and governance challenges.

  • 🧩 Coordination Still Evolving: Current structured messaging protocols can't support emergent, adaptive collaboration in large-scale multi-agent systems.

  • 🔐 Security & Discovery Gaps Persist: Agents often lack standardized methods for secure discovery and mutual trust, exposing hidden vulnerabilities.

🧑‍💻 CTO’s Lesson: Engineer Caught Using ChatGPT for Coding Sparks Broader Tech Policy Rethink

A viral case revealed a software engineer using ChatGPT for major coding tasks—but instead of disciplinary action, the CTO opted to address security policy gaps and set a precedent for responsible AI usage across the team.

Key Takeaways:

  • ⚠️ Security Over Usage: The CTO’s main worry wasn’t that AI was used—but that its generated code could contain vulnerabilities and proprietary data risks.

  • 🔍 AI Output as Starting Point Only: AI-generated code must be thoroughly reviewed, tested, and understood by human engineers before incorporation into production.

  • 🚨 Policy First, Not Bans: Rather than prohibiting AI tools entirely, the company established clear policies governing responsible use and data privacy.

  • 🤝 AI Productivity with Oversight: When used with governance and understanding, AI can boost developer output while keeping quality and security intact.

Why It Matters

As AI agents grow more capable, their ability to communicate clearly will define how far—and how fast—we advance. Without a shared language, even the smartest systems risk speaking past each other.

The future of agentic AI won't just depend on intelligence—it'll hinge on alignment.
