Enterprise Cyber Resilience

We meet you where you are on your CyberSecurity journey.

AI isn’t just changing how companies operate. It’s changing how they get attacked.

Security teams built their defenses around yesterday’s threats. Now they’re racing to keep up with a threat landscape that shifts every time a new model, tool, or integration gets adopted.

And the pressure doesn’t let up: every new AI feature a company ships expands the attack surface a little further.

We close the gap.

The SIS Cyber Approach

AI security blind spots aren’t a line item for us. They’re the whole business.

Every company building with AI has gaps that standard tools aren’t built to see, let alone close.

Everyone claims to help with blind spots. The difference is what happens next. Most will sell you a dozen tools or push an expensive governance framework and call it coverage. We don’t. We know the actual technology behind AI cybersecurity, so we can pinpoint exactly where you’re exposed. No bells and whistles, no unnecessary add-ons.

And because we work seamlessly within your existing workflow, fixing those problems doesn’t mean disrupting how your team already operates. The engagement is easy, frictionless, and made to measure.

AI SECURITY

AI Data Security Remediation

A global financial services firm rolled out Microsoft Copilot across its entire distributed workforce, giving employees AI-assisted access to its Microsoft 365 and Azure estate. Under an accelerated time frame, SIS Cyber implemented and tested security controls to prevent unrestricted access to data by Copilot, thereby reducing risk and increasing visibility and auditability, while still enabling high velocity innovation by the client’s knowledge workers.

The Challenge

The organization had recently rolled out Microsoft Copilot across teams with access to SharePoint, Outlook, and Teams, but had no visibility into whether the AI assistant could be manipulated into revealing sensitive information it wasn’t meant to surface. Leadership needed to understand their actual exposure to prompt injection and data exfiltration before an incident — not after.

Our Approach

1

Mapped risk categories specific to Copilot’s integration with SharePoint, Outlook, and Teams to define the scope of data access.

2

Conducted reconnaissance to determine what environment and data information Copilot could be prompted to reveal.

3

Engineered and refined prompt injection payloads targeting Copilot’s data access boundaries.

4

Developed test methodologies for data exfiltration exposure to validate real-word exploitability.

5

Assessed findings against client policy, data governance, and employee usage patterns.

6

Delivered mitigation recommendations spanning policy tuning, prompt governance, employee training, and technical controls.

Key Outcomes

Remediated exploitable prompt injection paths within the Microsoft 365 Copilot environment.

Implemented security controls for data exposure risks across SharePoint, Outlook, Teams, and Copilot Studio.

Delivered a prioritized mitigation roadmap covering policy, governance, and technical controls.

Gave leadership a clear, evidence-based picture of AI-related data security risk.

Application Security Architecture Review

Faced with a critical architectural review of their API-based web and mobile services, one fintech organization had a choice to make — and they chose SIS Cyber. Not because we were the only option, but because our team’s depth and creativity stood apart. The result: a fundamental shift in design strategy, moving the client from a product-first mindset to a process-first one built to last.

The Challenge

Real customer data was about to start moving through a freshly built API-based integration layer, and the design had never been tested by anyone outside the organization. Internal confidence was high — but internal confidence is also, by definition, a blind spot. Once live, any weakness in the architecture would be locked in, far harder to unwind than if it had been caught before launch.

Our Approach

1

Scoped the assessment around the AWS cloud platform and its related components.

2

Reviewed IAM configurations and access control design across the environment.

3

Evaluated API security, including authentication, authorization, and exposure points.

4

Assessed storage security and data-at-rest protections.

5

Mapped network boundaries and trust zones across the cloud architecture.

6

Examined secure integration patterns between cloud services and third-party systems.

7

Designed and led a hands-on hackathon, challenging the organization’s own team to stress-test their security design assumptions in real time.

Key Outcomes

Validated secure configuration across the AWS environment prior to launch.

Identified critical architecture gaps before they could be exploited in production.

Delivered risk-prioritized findings across IAM, API security, storage, and network boundaries.

Provided stakeholders with independent assurance and a clear remediation path before go-live.

Security Maturity

OWASP SAMM Assessments

SIS Cyber led OWASP SAMM assessments to baseline SDLC maturity and build targeted improvement roadmaps for financial services and manufacturing organizations, benchmarking their software development practices against industry best practices for security.

The Challenge

Across these organizations, the common thread was the same: multiple development teams working across various projects and different continents, each operating with different tooling and processes. Leadership needed a consistent, evidence-based view of security maturity that could be presented to regulators and the board — without disrupting delivery pipelines.

Our Approach

1

Facilitated structured interviews across disparate development teams using the OWASP SAMM interview model.

2

Scored maturity across all five SAMM business functions and 15 security practices.

3

Benchmarked results against industry peers.

4

Identified critical gaps in design review, security testing, and threat assessment.

5

Delivered a detailed improvement roadmap with 90-day, 6-month, and 12-month milestones.

6

Presented findings to CISO and board with executive-ready risk framing.

Key Outcomes

Clear maturity baseline established across development teams.

Regulatory-ready evidence package delivered for upcoming audit.

Highest-risk gaps prioritized first, cutting remediation costs by focusing effort where it mattered most.

Gave the board a repeatable, trackable maturity score — turning future security investment into something they can measure, not just discuss over time.

CNAPP Migration

SIS Cyber migrated a multi-national organization from Palo Alto Prisma Cloud to Wiz. Struggling with a SOC overwhelmed by alert fatigue, the client needed engineering expertise to automate the movement of policy configurations from the fragmented legacy systems without the manual rebuild typically required for a platform switch of this scale.

The Challenge

Prisma’s policy structure had fragmented over time, creating inconsistent enforcement and duplicated rules across the environment. The resulting alert volume had overwhelmed the client’s SOC, burying real signal in noise. No existing tool could translate Prisma’s policy configurations into Wiz’s format, meaning a full manual rebuild was the only standard option — a process that risked introducing gaps in coverage and taking months to complete.

Our Approach

1

Audited existing Prisma policies to identify fragmentation, redundancy, and gaps driving alert fatigue.

2

Mapped policy logic and coverage requirements against Wiz’s platform structure.

3

Built a custom API-driven migration path to translate and transfer policies directly, since no off-the-shelf tool existed for this transition.

4

Validated migrated policies against original coverage to confirm no gaps were introduced.

5

Preserved security posture and policy continuity throughout the cutover.

6

Supported go-live with zero operational downtime.

Key Outcomes

Successfully migrated policy configurations from Prisma to Wiz without a manual rebuild.

Eliminated the policy fragmentation driving SOC alert overload.

Maintained full policy continuity and security coverage throughout the migration.

Delivered the transition with zero operational downtime.
