Our guiding rules
Workshops, talks, and roundtables must provide solutions, strategies, or actionable insights that help overcome industry challenges or seize new opportunities.
S4S is a pitch-free zone. We prioritize trust and learning — not promotions. Every conversation exists to inspire, not to sell.
Sessions must remain neutral unless a product is essential to the solution being shared. The focus stays on knowledge, not marketing.
Everyone is here to grow. Whether you're a CISO, partner, or decision-maker — we engage respectfully and collaboratively, on level ground.
Partners may explore their services in one-on-one settings, but only through mutual interest and aligned challenges — never unsolicited.
We don’t dwell on known issues. S4S is for those ready to build, adapt, and lead — starting with answers, not complaints.
All conversations fall under the Chatham House Rule: content may be shared, but not the identity of the speaker. This ensures open and honest dialogue.
Membership isn’t open to everyone — it’s reserved for those who lead, inspire, and collaborate. Apply today and help shape the direction of the industry alongside peers who value innovation, insight, and transparency.

Synack’s premier security testing platform enables a vetted community of security researchers to deliver continuous penetration testing and vulnerability management, with transformational results. We are committed to reducing cybersecurity risk for our customers, bridging the cybersecurity talent gap and giving organizations on-demand access to improved security testing capacity and analytics on a single platform.
As your organization’s digital footprint scales and transforms, so too must your security testing. Whether driven by initiatives such as business transformation or more secure code deployments, truly strategic security testing requires on-demand access to scarce, highly skilled and diverse testing talent.
As you scale it becomes challenging to ensure vulnerabilities don’t exist and, oftentimes, to obtain the security testing coverage that matters most to your organization. This is due to noisy results, managing a high number of vendors and inefficient and disruptive reporting. In an ideal scenario, testing results are clearly communicated in ways that are actionable to internal teams, promote efficient remediation and help security leaders identify the root causes of vulnerabilities.
Furthermore, digital transformation brings with it a more dynamic attack surface: code deployments introduce new vulnerabilities, cloud environments evolve, compliance and regulatory requirements remain a priority, and APIs abound. Because of this dynamism, point-in-time security assessments are no longer representative of your holistic security posture over time. Plus, with the rising complexity of application architectures, it is unlikely that one or two testers will have sufficient expertise to cover complex architecture variations. More diverse skill sets are required.
Additionally, adversaries are becoming more sophisticated as breaches and ransomware increase in frequency. Announced vulnerabilities can be deployed as attacks by adversaries in minutes, faster than most organizations can respond.
These challenges give rise to the need for continuous, agile and effective security testing that can combat today’s adversaries with offensive techniques.
Synack has the experience and capabilities to help organizations at every stage of their digital transformation.
