Security services for applications and SaaS
Comprehensive Application Security Services for IT Companies
Software as a Service (SaaS) is a key factor in the development of modern information technology. Therefore, SaaS is naturally a significant driver of IT risks on the planet.
With our superb DevSecOps competencies and experience in helping dozens of SaaS vendors and IT product developers, we effectively mitigate SaaS risks with our services.
According to Gartner’s estimates, SaaS is the main driver of growth for the entire IT market. But as the popularity grows, so do the number of published vulnerabilities in IT services and various problems of ensuring the protection of cloud environments from cybercriminals.
As SaaS adoption grows, control shifts to end users and customer admins — where misconfigurations and misuse are most common. In SaaS, risk concentrates around roles, sessions, tokens, and APIs.
- Auth / session: weak MFA, flawed SSO/OAuth flows, long-lived sessions, leaked refresh tokens, missing device/context binding, unsafe account switching.
- RBAC / ABAC: overly broad default roles, no separation of duties, permission inheritance issues, privileged actions without step-up auth, no break-glass process.
- Shadow integrations: users connect third-party apps via OAuth/API keys, creating unmanaged data-exfil channels.
- Insider actions: exports, bulk deletes/updates, sharing changes, audit log tampering — often indistinguishable from “legit” activity without proper monitoring.
In SaaS, the most critical failure is breaking tenant boundaries — a single tenant-context bug can become cross-tenant access.
- Application isolation: tenant-context bugs (IDOR, tenant_id spoofing), unsafe global queries, row-level security gaps, shared cache/job queue leakage.
- Infrastructure isolation: shared DB/cluster/storage, shared secrets, missing network segmentation.
- Collaboration & sharing: public links, guest access, shared spaces, permission templates — frequent sources of accidental exposure.
- Backups & exports: backups, snapshots, analytics stores, search indexes, and logs can become bypass paths to sensitive data.
Secrets are the lifeblood of SaaS: tokens, keys, passwords, certificates, signing keys, KMS. They usually leak through process gaps, not “advanced hacking”.
- secrets in repos, CI logs, env vars, helm values, IaC;
- one key for everything instead of environment/tenant separation;
- weak rotation, no secret scanning, over-privileged service accounts;
- insecure storage/issuance of integration tokens (webhooks, API keys, PATs).
SaaS ships fast, so the software supply chain becomes a prime attack surface.
- CI/CD: artifact tampering, compromised runners, unsafe pipelines, missing artifact signing, weak deploy permissions.
- Dependencies / containers: vulnerable or compromised packages, typosquatting, CVEs in base images, missing SBOM and patch policy.
- IaC: Terraform/CloudFormation mistakes, config drift, uncontrolled console changes.
Many incidents start with cloud misconfigurations rather than zero-days.
- public buckets/snapshots, overly permissive security groups, exposed admin consoles;
- excessive IAM privileges, missing boundary policies, unprotected metadata endpoints;
- weak WAF/rate limiting, poor API protection, lack of segmentation;
- weak encryption settings, unrestricted key usage.
Even strong controls fail without observability, incident readiness, and clear data governance.
- Logging & audit: incomplete audit trails (who, what, when, where from, where to), no action correlation, weak retention, logs not protected from tampering.
- IR readiness: no runbooks, no forensics readiness, untested scenarios (token leak, admin takeover, mass export).
- Data residency & governance: where data actually lives (primary, backups, logs, analytics), deletion/retention enforcement, subprocessor management, GDPR/DPA/enterprise requirements.
- Standards selection: trying to “do everything” (SOC 2 + ISO 27001 + NIST + CIS + industry regs) without control mapping becomes expensive and chaotic; you need a minimal baseline that covers the broadest set of customer demands.
Our mission is to help cloud developers and providers, as well as SaaS users, ensure and maintain security. H-X professionals will quickly and efficiently audit the security of your applications and infrastructure and verify their compliance with security standards and regulations. If you are just considering migrating your solution to the cloud, we will help you design and migrate considering cybersecurity standards and best practices.
