Traceguard

TraceGuard helps enterprises and regulated organizations manage software supply-chain risk with clarity and confidence. Modern software relies on thousands of third-party components and vendors. While many security tools generate long lists of vulnerabilities and alerts, organizations need more than visibility, they need to understand what truly matters, what the impact is, and what decisions to make next. TraceGuard combines SBOM data, vulnerability intelligence, vendor context, and decision tracking to turn fragmented signals into clear, explainable decision signals. This enables teams to move from reactive vulnerability management to predictive supply-chain risk management, before issues escalate into incidents, audit findings, or reputational damage. TraceGuard makes software supply-chain risk measurable, actionable, and explainable.

Custodes

Custodes is het plug-and-play cybersecurityplatform voor het MKB én hun MSP’s. Veel organisaties hebben antivirus en een firewall, maar missen inzicht in hun échte risico’s, compliance-status en wat er gebeurt als een aanval tóch binnenkomt. Custodes maakt dat wél zichtbaar! Eenvoudig, betaalbaar en zonder complexe implementatie. Met één security-appliance achter de router krijgt elke organisatie directe grip op digitale risico’s. Binnen 30 minuten live, zonder software op endpoints. Custodes bundelt 6 essentiële modules in één platform: 1. Technische & netwerkscans – continu inzicht in kwetsbaarheden en duidelijke actiepunten. 24/7 hacker-alerts – sensoren die indringers en afwijkend gedrag direct detecteren. Phishing-simulaties & awareness – realistische campagnes die risico’s per medewerker en afdeling meten. Compliance-dashboards (helpen met AVG/NIS2/ISO) – audit-klare rapportages en werkbaar beleid. Microsoft-integraties – inzicht in o.a. MFA, externe deling, auto-forwards, risky logins en app-permissions. Vendor Risk Management – beoordeling van leveranciers en ketenrisico’s. Voor MSP’s is Custodes partner-first: • Multi-tenant dashboard voor al je klanten • MSP behoudt de volledige klantrelatie • Eén platform i.p.v. meerdere losse tools Custodes is ideaal voor MKB’s met 10–500 medewerkers in o.a. zakelijke dienstverlening, productie, zorg, logistiek, tech en retail. Organisaties die te groot zijn om risico’s te negeren, maar te klein voor een volwaardig SOC. Custodes: inzicht, controle en weerbaarheid voor het MKB, samen met MSP’s.

The payment terminals would be deeply embedded in their infrastructure, as well as handle large amounts of customer data. So before deploying thousands of them, we were asked to analyze the device to identify potential security issues. Together with the vendor of the terminal, we worked on resolving the findings - Providing our client with a more secure device and peace of mind- Smart Safe Testing: A renowned provider of safes and cash management solutions asked to evaluate the security of their smart safe. With decades of experience in physical security, they offer their customers the highest assurance on their products. To ensure that the cybersecurity is of the same level that their customers have come to expect, we were asked to evaluate the product. During our testing, both hardware and software attacks on the electronics were considered. Issues that were found were quickly addressed and by retesting we were able to confirm the efficacy of the fixes. By combining our expertise, the client can be as confident about the cybersecurity of the safe as they are about its physical security
