Olimpio Security

Olimpio is an external vulnerability scanner built for UK small businesses. It scans your domain for security weaknesses — open ports, missing email authentication records, expired SSL certificates, HTTP security headers, exposed API keys, and known software vulnerabilities — and explains every finding in plain English with clear remediation steps. Most vulnerability scanners are built for enterprise security teams with technical staff to interpret the results. Olimpio is different. Results are explained in plain English so business owners and non-technical managers can understand exactly what is wrong and how to fix it. Key features: external port scanning (standard and deep mode), DNS and email security checks (DMARC, SPF, DKIM), SSL certificate monitoring, HTTP security header analysis, GitHub secrets scanning for exposed API keys, Cyber Essentials control mapping (CE1–CE5), AI-generated plain-English finding explanations, PDF security reports, and security score tracking over time. Free tier available. Starter plan from £49/month.

Oxeye Application Security Platform

Oxeye is an application security solution that was developed to address the unique architecture of cloud native applications. We combine static analysis with runtime flow tracing and infrastructure analysis. Using this multilayered approach, we provide a contextual analysis of vulnerabilities, and prioritize them based on their severity. For greater insights, we report whether third party packages are loaded or not, show infrastructure configuration, and graphically show users the vulnerable flow from the internet to a particular line of code, for quicker remediation. With Oxeye, false positives, and false negatives, become a thing of the past. Installation generally takes less than 5 minutes, and does not require changes to the code or the deployment of any software packages. All that’s required is the deployment of a container within your environment. Once running, Oxeye will automatically scan the environment and provide all of the analysis on its own.

PRISM Recon

PRISM Recon watches what your company exposes to the internet, so your team doesn't have to. Add your domains and PRISM checks them every week, automatically. There's nothing to install or maintain, and you only hear from us when something changes, like newly exposed services, expiring certificates or weakened email settings. Every scan comes with a report that's already written: plain-English findings, a single risk score, prioritized fixes, and a clear view of what changed since the last scan. It's ready in seconds to hand to your team, leadership or stakeholders, and MITRE ATT&CK mapping is included in every report. PRISM fills the gap between pen tests and audits. New exposures show up within a week, not at next year's assessment. It also gives you an independent way to check your vendors' work and catch assets a hosting provider or IT partner left exposed by accident. Scanning is non-intrusive: no exploits, no login attempts, and nothing is changed on your systems. Data is encrypted, and full reports are kept for 60 days. MSPs and MSSPs can use it across client domains too. Start a 14-day free trial: 3 full scans, no credit card.

Raven.io

Runtime Application Protection | Stop Exploits Before They Run Raven protects applications at runtime — the layer where attacks actually happen. Whether a CVE exists or not. 70% of attacks arrive with no CVE at time of exploitation. WAFs see traffic but not execution. EDR sees processes but not library behavior. SCA catches known CVEs but misses everything else. Traditional security tools are blind to what is actually executing inside your applications — and that is where modern attacks live. Raven closes that gap. Raven gives security teams unprecedented visibility into how applications, libraries, and functions actually behave in production — without code changes, code injection, or application restarts. See exactly which libraries are executing, how they chain together, and whether that behavior is legitimate or malicious. What Raven does: Runtime ADR — Detect and block application-layer attacks including CVE-less exploits, supply chain compromises, and AI-generated threats at the point of execution. Runtime SCA — De-prioritize up to 99% of CVE noise by identifying which vulnerable libraries are actually executing in production versus present but dormant. Runtime AI-DR — Discover, monitor, and control every AI agent operating in your environment. Runtime Gatekeeper — Predict and block dangerous deployments before they reach production. Deployment: Kubernetes-native. Single Helm chart. No code changes. No restarts. Near-zero performance impact. Supports Java, Python, Node.js, Go, Ruby, PHP, and all JVM-based languages. Any cloud. Linux kernel 4.18+.
