Red Teaming Penetration Testing Phishing Attack Simulation
Red Teaming

Red Teaming

Improve your enterprise’s ability to defend against real threats like Ransomware attacks.

Don’t stop at Pentests and Security assessments! Red Teaming fully tests the strengths of your security systems and prepares your defensive team to deal with sophisticated attacks performed by security professionals who know real-world tactics to compromise environments.

The adversary emulation exercises help you understand how far a malicious actor could move into your network exploiting vulnerabilities. So, you can prepare your strategy, practicing response methods, in the event of a targeted attack.

Contact us
Penetration Testing

Penetration Testing

Determine whether a combination of flaws & vulnerabilities can be exploited to compromise the application, its data, or its environment resources.

We research security vulnerabilities in Web/Mobile applications as well as Applications Programming Interfaces (API) to gain unauthorized access to your sensitive data or trigger malicious behaviors. Then we help developers in fixing issues to protect your organization and customers.

In addition, we test industrial devices (OT) to address and mitigate risks in critical production systems. We provide recommendations to prevent attackers from damaging infrastructures or threatening people’s lives.

Phishing Attack Simulation

Phishing Attack Simulation

Humans are the weakest link in the security chain and the major access point for cyber-attacks. We test employees with tailor-made phishing emails built on real-world attacks, helping them to recognize and avoid phishing scams.

A real-time learning Pill appears upon a wrong behavior, describing phishing techniques & providing recommendations to avoid falling victim to cybercriminals.

CYS4 draws up a final report with PiII securely processed and anonymized, aggregating the metrics by department, and identifying the ones requiring further training on phishing topics: we aim to improve your workforce resilience against phishing attacks, acting in time to educate personnel and protect the company’s data.

Compromise Assessment

Compromise Assessment

Get to know if your organization got breached. Identify ongoing and past attacks, increasing your ability to respond effectively to future incidents.

A new APT may evade your cybersecurity solutions, attackers could move laterally in your network, gain access to your systems in a few minutes and stay undetected for a long time. We hunt for any evidence of malicious actors' activities in your perimeter, analyzing logs, monitoring network traffic, and inspecting endpoints as well as emails.

Proactive assessments reduce the risk of noticing a compromise too late, allowing your organization to respond quickly and effectively.

Equixly

APIs can pose a serious risk to organizations without proper security controls, since they are designed for machine-to-machine data exchange, representing a direct route to sensitive data.

Equixly aims to help developers and organizations create more secure applications, increase their security posture, and spread knowledge of new vulnerabilities.

Equixly makes available a SAAS platform that allows integrating the API security testing within the software development lifecycle (SLDC) to detect flaws, reduce bug-fixing costs and exponentially scale penetration testing upon every new functionality released. The platform can automatically perform several API attacks leveraging a novel machine learning (ML) algorithm trained over thousands of security tests. Finally, Equixly returns a near-real time results and a predictive remediation plan that developers may use to fix their application issues autonomously.

The Equixly advanced platform and its innovative security testing approach take an organization's API security maturity to the next level.
