What it does
ThreatPort continuously monitors your attack surface so you know what's exposed before someone exploits it. ThreatPort automatically scans your domain for: • Open ports - risky services • Exposed sensitive files (.env,git, credentials) • SSL/TLS misconf. • DNS vulnerabilities (SPF, DMARC, DKIM) • Leaked API keys in page • CORS misconfigs. • Subdomain enum. Brand Protection No setup required. Enter your domain, get your first report in minutes. Free tier available — no credit card needed.
Discover exposed assets, open ports, CVEs, SSL, DNS and email security risks with ThreatPort
ThreatPort helps IT managers, CISOs, CTOs, and lean security teams understand what is exposed on the public internet before attackers, auditors, or customers find it. The platform combines external attack surface management, cyber threat intelligence, CVE mapping, DNS and email security checks, SSL monitoring, open port visibility, and AI-assisted pentest reporting in a self-serve workflow. Teams can start with a free domain scan to discover subdomains, exposed services, weak headers, missing SPF or DMARC records, certificate issues, and technologies that may be linked to known vulnerabilities. ThreatPort is agentless, does not require installation, and is designed for organizations that…from threatport.com

SecureNowDec 2025 · securenow.dev · ▲6Hi HN, I'm an Indie Dev. Building web apps, I struggled to check for vulnerabilities on a surface and a deeper level at the same time. Most free scanners gave vague results or missed dependency issues and tools for deeper searches are mainly for enterprise. Also with vibe coding the issue of security is rising more and more. I built SecureNow - a simple web scanner built with Next.js and Supabase that checks SSL, ports, dependencies, headers, and basic vulns. It caught real issues in my projects. Free basic scans at securenow.app. Feedback on accuracy and missing features? Thanks!

Talanoa▲346Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

Hey HN, Henry here from Cactus. We open-sourced Needle, a 26M parameter function-calling (tool use) model. It runs at 6000 tok/s prefill and 1200 tok/s decode on consumer devices. We were always frustrated by the little effort made towards building agentic models that run on budget phones, so we conducted investigations that led to an observation: agentic experiences are built upon tool calling, and massive models are overkill for it. Tool calling is fundamentally retrieval-and-assembly (match query to tool name, extract argument values, emit JSON), not reasoning. Cross-attention…
