Learn moreAs cloud environments integrate AI, the attack surface expands. Beyond misconfigurations and risky OAuth connections, organizations now face prompt injections, misuse of AI agents, and over-privileged access. Discover intelligence-driven SaaS security to find and fix exposures early, govern AI usage, and contain abuse across your SaaS and AI-integrated environments.
API vulnerabilities and cloud misconfigurations have become the most common risks in the enterprise, drastically expanding the SaaS attack surface. Security teams can no longer rely on fragmented controls that miss the gaps between applications. Group-IB’s SaaS security solutions extend protection across the full environment, from SaaS apps and AI copilots to the APIs and cloud infrastructure that power them. Our unified platform delivers the continuous monitoring and actor-aware enrichment needed to spot exposures early and stop breaches fast.
M365, Google Workspace, and other SaaS suites are key targets for credential theft, Business Email Compromise (BEC), and malware distribution. Targeted phishing campaigns exploit weak authentication and stolen sessions to impersonate users, escalate privileges, and access sensitive data across connected applications.
of organizations reported experiencing unauthorized SaaS access.
Business Email Protection stops phishing attempts, malicious attachments, and credential harvesting targeting SaaS accounts. Advanced threat detection analyzes email content, sender reputation, and behavioral patterns to intercept attacks exploiting SaaS authentication.
Digital Risk Protection monitors your brand’s digital presence for look-alike domains, fake login pages, rogue apps and plugins, social impostors, and leaked credentials. Real-time alerts and takedown workflows remove malicious assets and shut down the routes attackers use to hijack SaaS accounts.
Threat Intelligence adds actor-aware context for campaigns that target SaaS. Integrations push indicators into your controls so you can block phishing domains, look-alike infrastructure, command and control endpoints, and risky OAuth app IDs. It tracks data leak sites and stealer logs for exposed corporate credentials so teams can enforce password resets, revoke sessions/tokens, and remove risky OAuth grants.
Managed XDR delivers 24/7 monitoring and incident response across SaaS, identity, cloud, and endpoints. It correlates activity across these surfaces to uncover early signs of compromise, from credential misuse and consent abuse to data exfiltration and ransomware staging. Our analysts then enrich alerts with threat-actor context, contain active sessions, and orchestrate rapid remediation to prevent breaches and data loss.
Modern SaaS apps communicate heavily via APIs. Each exposed or misconfigured API endpoint becomes a potential exploit route. This risk is compounded by Shadow SaaS (unauthorized applications that bypass IT review) and hidden threats in the software supply chain. Compromised third-party libraries and dependencies within connected services introduce vulnerabilities deep inside your ecosystem. Unvetted OAuth apps and over-privileged service accounts leverage these hidden entry points to facilitate SaaS-to-SaaS lateral movement.
of incurred compute fees from misused OAuth applications for cryptomining by the threat actor, Storm-1283.
Threat Intelligence monitors code repositories and developer sources to detect exposed API keys, tokens, and credentials before attackers can weaponize them. Correlate findings to your tenants and scopes, flag risky apps, and track attacker infrastructure tied to SaaS abuse, including AI-driven risks.
Vulnerability Assessment examines SaaS configurations, shadow SaaS usage, API permission structures, and third-party integrations to identify over-privileged apps and supply chain gaps. Detailed reports prioritize risks and provide remediation guidance for strengthening your SaaS security posture.
Penetration Testing evaluates the security of your SaaS applications and integrations through controlled attacks. Security experts identify exploitable weaknesses in OAuth implementations, API endpoints, and underlying dependencies before malicious actors can exploit them.
While the cloud provides SaaS companies with unparalleled convenience and scale, security is often compromised in the process. Rapid deployment frequently leads to misconfigured storage, open ports, and permissive access policies. Without continuous monitoring, these infrastructure gaps create open doors for attackers to compromise the underlying environment that supports your SaaS applications.
of cloud breaches will be due to misconfigured resources and insufficient posture management by 2026.
Cloud Security Posture Management (CSPM) ensures continuous compliance and risk monitoring across multi-cloud environments. It helps prevent SaaS and API breaches caused by misconfigured cloud infrastructure by detecting risks in real-time and automating policy enforcement.
Attack Surface Management maps your entire external footprint to find what your security team doesn’t know exists. It autonomously discovers Shadow IT, forgotten cloud instances, and exposed databases that fall outside standard compliance checks, ensuring no asset is left unprotected.
Compromise Assessment is a proactive deep-dive into your cloud infrastructure to answer the critical question: “Are we already breached?” Group-IB threat hunters analyze your environment for dormant threats, established backdoors, and signs of past intrusions that automated tools may have missed.
As SaaS environments integrate AI agents and copilots, the pathways for data theft have multiplied. Techniques like prompt injection can trick AI models into leaking sensitive corporate data, while misused AI agents can be manipulated to perform unauthorized actions. These complex, automated threats often bypass traditional controls and require deep, cross-signal correlation to detect. Furthermore, regulators still hold the data owner responsible (not the SaaS vendor) for ensuring data protection and compliance. Without unified visibility, both covert data theft and regulatory violations go undetected.
the average cost of data theft, which rises significantly when automated systems and AI are involved in the exfiltration.
Managed XDR combines behavioral analytics, threat intelligence, and expert analysis to identify suspicious activity across your SaaS and AI ecosystems. 24/7 security operations teams investigate unusual access patterns, prompt injection attempts, and anomalous data movements to stop exfiltration before damage occurs.
Prevent breaches and shadow IT with a single platform. The Unified Risk Platform provides complete coverage to uncover unmanaged AI applications, over-privileged agents, and hidden SaaS risks, optimizing your security posture through Group-IB defenses.
Vulnerability Assessment provides a comprehensive security audit to ensure your SaaS environment is compliance-ready. Experts audit data storage locations, access privileges, and third-party integrations to eliminate security blind spots. We validate your SaaS configurations against frameworks like GDPR, NIST, and CIS to ensure full compliance.
Attackers create convincing replicas of legitimate SaaS login pages to harvest credentials from unsuspecting users. These phishing portals appear in search results, QR codes, social media, and targeted email campaigns. Brand impersonation attacks exploit user trust to capture credentials and multi-factor authentication codes.
phishing attacks reported in Q1 2025, the largest quarterly total since Q4 2023.
Digital Risk Protection scans the internet for fake login portals, phishing pages, and brand impersonation attempts targeting your SaaS applications. Automated takedown capabilities remove malicious infrastructure before it can harvest employee credentials.
