Open-source security consulting helps organisations deploy, configure, and operate enterprise-grade security tools — SIEM, IDS/IPS, vulnerability management, and threat intelligence platforms — without commercial licensing costs. White Aegis specialises in implementing and supporting open-source security platforms for businesses globally, delivering the same security outcomes as commercial alternatives at a fraction of the total cost.
The cybersecurity market is built around a pricing model that does not scale with small and mid-size organisations. Enterprise security platforms charge per endpoint, per user, per data volume, or per feature tier — costs that compound quickly as organisations grow. A SIEM licence for 500 endpoints. A separate EDR licence per device. A threat intelligence feed subscription. A vulnerability management platform on top of that. Before any of these tools have been properly configured, the annual spend can reach hundreds of thousands of dollars.
Open-source security tools break this model. The software is free. What you pay for is the expertise to implement it correctly, tune it to your environment, and operate it effectively — which is where the actual security value comes from anyway.
Open-source does not mean unsupported, unproven, or unsuitable for enterprise use. The most widely deployed security tools in the world — including many running inside Fortune 500 companies and government agencies — are open-source. What it means is that the source code is publicly maintained, independently audited by thousands of contributors, and free from commercial licensing terms that make scaling expensive.
The trade-off is implementation expertise. Open-source platforms require skilled configuration to deliver their full capability. Default installations are never production-ready — correlation rules need tuning, log sources need integration, alert thresholds need calibration. This is exactly where White Aegis adds value.
One of the most widely deployed open-source security platforms in the world, providing SIEM, XDR, and compliance monitoring in a single platform. Integrates with cloud environments, containers, and on-premises infrastructure, and ships with pre-built compliance dashboards for PCI-DSS, ISO 27001, GDPR, and HIPAA. We implement, configure, and tune Wazuh to production standard — including custom detection rules, log source integration, and alert routing.
An enterprise-grade network threat detection engine capable of intrusion detection (IDS), inline intrusion prevention (IPS), and network security monitoring at wire speed. We deploy Suricata in monitoring or prevention mode, configure rulesets tuned to your network profile, and integrate it into your security monitoring workflow.
Comprehensive vulnerability scanning across network devices, servers, applications, and endpoints with a continuously updated feed of over 100,000 vulnerability tests. Produces risk-rated findings that map to CVSS scoring and compliance frameworks. We deploy and configure OpenVAS for your environment and integrate findings into your remediation workflow.
An open-source security incident response platform providing case management, task assignment, evidence tracking, and analyst collaboration. Integrates with MISP for threat intelligence and with SIEM platforms for automated case creation. We implement TheHive as the workflow layer for your incident response process so every alert triggers a consistent, documented response.
The standard open-source platform for threat intelligence management and sharing — used by CERTs, financial sector ISACs, and government agencies worldwide including CERT-In's IB-CART network. We implement MISP to ingest external threat intelligence feeds, manage internal indicators of compromise, and share intelligence with sector peers where applicable.
Centralised, audited secrets management with dynamic credential generation, automatic rotation, and fine-grained access policies. We implement Vault for organisations moving to cloud-native and DevSecOps environments where hardcoded credentials in code repositories are a persistent risk.
We implement both open-source and commercial platforms. Our recommendation is always based on what delivers the right security outcome for your organisation — not what generates the most revenue for us.
Most organisations benefit from a hybrid approach — open-source for foundational capabilities like SIEM and vulnerability management, commercial where a specific capability gap justifies the cost. White Aegis helps you make this decision with clear data, not vendor preference.
A common misconception is that open-source tools cannot meet regulatory compliance requirements. In practice, platforms like Wazuh ship with pre-built compliance dashboards for the most common frameworks.
Yes — provided it is implemented and maintained correctly. Many of the most widely deployed security platforms in the world are open-source, including tools used by government agencies, financial institutions, and Fortune 500 companies. Open-source code is publicly reviewable, which means vulnerabilities are identified and patched by a global community — often faster than commercial vendors patch proprietary code. The risk is not in the software being open-source; it is in deploying it without proper configuration and ongoing maintenance.
The software itself is free — the cost is implementation and ongoing support. A Wazuh deployment that delivers comparable coverage to a commercial SIEM typically costs significantly less in total over a three-year period, even accounting for implementation and support fees. The exact comparison depends on your scale and requirements. White Aegis provides a cost comparison as part of every assessment so you can make the decision with accurate numbers.
Yes. Wazuh ships with pre-built compliance dashboards for PCI-DSS, ISO 27001, GDPR, HIPAA, and NIST. OpenVAS produces CVSS-rated vulnerability reports that satisfy audit requirements. TheHive provides the documented incident management workflow auditors look for. We have implemented open-source security stacks that have passed ISO 27001 certification audits, PCI-DSS assessments, and SOC 2 reviews. Compliance is about evidence and controls — not whether the tool has a commercial logo.
We only recommend open-source platforms with strong, active community support and — in the case of tools like Wazuh and Greenbone — commercial entities behind them providing long-term maintenance. As part of every engagement, we document the tool's maintenance status and help establish a technology refresh plan. If a tool reaches end-of-life, migrating to a successor is typically straightforward because your data and configurations are not locked into a proprietary format.
Yes. We offer ongoing support retainers covering rule updates, new log source integrations, platform upgrades, performance tuning, and analyst support. Some clients handle day-to-day operations themselves and engage us quarterly for optimisation reviews. Others prefer a more continuous support arrangement. We design the support model around what you actually need.
If you are paying commercial licensing costs for security tools you are not fully using — or if cost has been the barrier to investing in security — open-source may be the answer. Contact White Aegis to discuss your requirements. We will assess whether open-source tools can meet your security and compliance needs, and give you a realistic cost comparison before you make any decision.
