What is HeaderKit?
HeaderKit is a focused web-header utility for teams that want to observe Content Security Policy violations before changing enforcement. It helps prepare CSP Report-Only policy packs and related review material so site owners can inspect what browsers would report while keeping the site behavior non-blocking.
HeaderKit is intentionally not a WAF, firewall, intrusion-prevention system, or general monitoring platform. It does not automatically enforce a policy, promise that a site is secure, or replace testing in each deployment environment. Review generated policy text, expected third-party resources, and browser reports before deciding what to deploy. Keep the policy under your own change control.
HeaderKit is sold for US$29 one time via Paddle. Use only authorized site information and do not submit credentials, tokens, API keys, or other secrets. The product is intended for developers and site owners who need a cautious Report-Only starting point for CSP work. Contact: idealstoronto@gmail.com. Honest scope matters: this is visibility and preparation for CSP Report-Only, not a WAF or auto-enforcing security product.
What problem it solves
Teams need visibility into CSP violations before changing enforcement. HeaderKit helps prepare Report-Only policy packs for review without acting as a WAF.
Alternatives & competitors
Manual CSP headers, browser devtools, and CSP reporting services. HeaderKit is Report-Only and not a WAF.
What is Resemble AI?
As generative AI makes convincing fake audio, images and video trivial to produce, a new problem has arrived: how do you tell what's real? Resemble AI has grown into a leading answer — a generative-AI security platform built to detect and verify synthetic media across audio, image and video before it can be used to defraud or deceive.
Detect deepfakes with high accuracy
At the heart of Resemble AI is Resemble Detect, a multimodal deepfake-detection engine that covers 160+ generative AI models and claims industry-leading accuracy (98.1% on audio benchmarks). Rather than a simple yes/no, it processes files to provide in-depth analysis explaining why something was flagged, which is exactly what security and fraud teams need to act with confidence. As voice-cloning scams and video deepfakes proliferate, that kind of reliable detection is quickly moving from 'nice to have' to essential.
Watermark and prove authenticity
Detection is only half the battle, so Resemble AI also offers watermarking technology that marks synthetic media and is compliant with EU AI Act requirements. That lets organizations both catch malicious fakes and responsibly label their own AI-generated content — increasingly a legal obligation, not just good practice. Real-time monitoring tools round out the picture, so threats can be caught as they emerge rather than after the damage is done.
Enterprise-ready deployment
Resemble AI is built for serious environments, with integration options for on-premises or cloud deployment so it can fit into strict security architectures. That flexibility matters for the banks, telcos and platforms that most need deepfake defenses and can't simply pipe sensitive media through an external service without control.
Ahead of a growing threat
The whole product is a bet that synthetic-media fraud becomes a mainstream security concern — a bet that looks more correct every month as deepfake scams make headlines. Getting ahead of it is far cheaper than cleaning up after a successful attack.
Who it's for
Resemble AI suits enterprise security leaders, developers, media organizations, financial institutions, telecommunications companies and marketplace platforms that need to protect against synthetic-media fraud and deepfake attacks.
Pricing
Resemble AI is freemium, with free-tier access to try it and paid enterprise plans for production-scale deployment; specific pricing is handled through their sales team given the enterprise focus. The free tier lets you test detection before committing.
Bottom line: Resemble AI is a generative-AI security platform for the deepfake era — high-accuracy detection across audio, image and video, plus compliant watermarking and real-time monitoring, built for organizations that can't afford to be fooled by synthetic media.
