Your attack surface is the sum total of all attack vectors that can be used against your perimeter defenses. It is simply the amount of information that you are exposing the outside world. The attack surface is the most important thing hackers will need to exploit to break into your network. When attacking targets, professional hackers usually follow the cyber kill chains. Typically, the first step in this process is to survey the target's attack surfaces. This is called advanced reconnaissance. By reducing the attack surface, you can reduce the risk and prevent attacks from ever happening. The cyber kill chain is a method for categorizing and tracking all stages of a cyberattack, from early reconnaissance to the exfiltration data.

It helps security teams reduce risk and improve key metrics like Mean Time to Detect (MTTD) by optimizing threat detection coverage while lowering Total Cost of Ownership (TCO) through native data routing and tiering. Additionally, Graylog Security accelerates incident response by enabling analysts to quickly address critical alerts, reducing Mean Time to Response (MTTR). With integrated SOAR capabilities, Graylog Security automates repetitive tasks, orchestrates workflows, and enhances response efficiency, empowering organizations to proactively detect and neutralize cybersecurity threats.

Ambassador Edge Stack, a Kubernetes-native API Gateway, provides simplicity, security, and scalability for some of the largest Kubernetes infrastructures in the world. Ambassador Edge Stack makes it easy to secure microservices with a complete set of security functionality including automatic TLS, authentication and rate limiting. WAF integration is also available. Fine-grained access control is also possible. The API Gateway is a Kubernetes-based ingress controller that supports a wide range of protocols, including gRPC, gRPC Web, TLS termination, and traffic management controls to ensure resource availability.

The premier hybrid and multi-cloud platform offers an advanced suite of security features including next-gen WAF, API Security, RASP, Enhanced Rate Limiting, Bot Defense, and DDoS protection, specifically engineered to address the limitations of outdated WAF systems. Traditional WAF solutions were not built to handle the complexities of modern web applications that operate in cloud, on-premise, or hybrid settings. Our cutting-edge web application firewall (NGWAF) and runtime application self-protection (RASP) solutions enhance security measures while ensuring reliability and maintaining high performance, all with the most competitive total cost of ownership (TCO) in the market. This innovative approach not only meets the demands of today's digital landscape but also prepares organizations for future challenges in web application security.

You can use your favorite debugging software to locally troubleshoot your Kubernetes services. Telepresence, an open-source tool, allows you to run one service locally and connect it to a remote Kubernetes cluster. Telepresence was initially developed by Ambassador Labs, which creates open-source development tools for Kubernetes such as Ambassador and Forge. We welcome all contributions from the community. You can help us by submitting an issue, pull request or reporting a bug. Join our active Slack group to ask questions or inquire about paid support plans. Telepresence is currently under active development. Register to receive updates and announcements. You can quickly debug locally without waiting for a container to be built/push/deployed. Ability to use their favorite local tools such as debugger, IDE, etc. Ability to run large-scale programs that aren't possible locally.

Resurface is a runtime API security tool. Resurface continuous API scanning allows you to detect and respond in real time to API threats and risks. Resurface is a purpose-built tool for API data. It captures all request and response payloads, including GraphQL, to instantly see potential threats and failures. Receive alerts about data breaches for zero-day detection. Resurface is mapped to OWASP Top10 and alerts on threats with complete security patterns. Resurface is self-hosted and all data is first-party. Resurface is the only API security system that can be used to perform deep inspections at scale. Resurface detects active attacks and alerts them by processing millions of API calls. Machine learning models detect anomalies and identify low-and slow attack patterns.

Akto is an open source, instant API security platform that takes only 60 secs to get started. Akto is used by security teams to maintain a continuous inventory of APIs, test APIs for vulnerabilities and find runtime issues. Akto offers tests for all OWASP top 10 and HackerOne Top 10 categories including BOLA, authentication, SSRF, XSS, security configurations, etc. Akto's powerful testing engine runs variety of business logic tests by reading traffic data to understand API traffic pattern leading to reduced false positives. Akto can integrate with multiple traffic sources - Burpsuite, AWS, postman, GCP, gateways, etc.

Pynt, an innovative API Security Testing Platform, exposes verified API threats by simulating attacks. We help hundreds companies, including Telefonica, Sage and Halodoc to continuously monitor, categorize and attack poorly secured APIs before hackers do. Pynt’s uses a unique hacking technology and an integrated shift-left strategy, using home-grown attack scenario, to detect real threats. It also helps to discover APIs and suggest fixes for verified vulnerabilities. Pynt is trusted by thousands of companies to protect the No. As part of their AppSec strategies, a number of companies rely on Pynt to secure the no.

Utilihive, a cloud-native big-data integration platform, is offered as a managed (SaaS) service. Utilihive, the most popular Enterprise-iPaaS (iPaaS), is specifically designed for utility and energy usage scenarios. Utilihive offers both the technical infrastructure platform (connectivity and integration, data ingestion and data lake management) and preconfigured integration content or accelerators. (connectors and data flows, orchestrations and utility data model, energy services, monitoring and reporting dashboards). This allows for faster delivery of data-driven services and simplifies operations.

Enterprise Single Sign On (SAML/OIDC SSO) 2. Directory Sync 3. Audit Logs 4. Data Privacy Vault (PII, PCI, PHI compliant)

open-appsec is an open-source initiative that builds on machine learning to provide pre-emptive web app & API threat protection against OWASP-Top-10 and zero-day attacks. It can be deployed as add-on to Kubernetes Ingress, NGINX, Envoy and API Gateways. The open-appsec engine learns how users normally interact with your web application. It then uses this information to automatically detect requests that fall outside of normal operations, and sends those requests for further analysis to decide whether the request is malicious or not. open-appsec uses two machine learning models: 1. A supervised model that was trained offline based on millions of requests, both malicious and benign. 2. An unsupervised model that is being built in real time in the protected environment. This model uses traffic patterns specific to the environment. open-oppsec simplifies maintenance as there is no threat signature upkeep and exception handling, like common in many WAF solutions.
