Single sign-on concentrates trust, so one flaw in the flow can unlock every connected application. We test OAuth 2.0, OpenID Connect and SAML implementations for Cyprus apps against the subtle mistakes that lead to account takeover.
We assess your identity provider and relying parties together — where most real bugs live — covering redirect handling, token validation and assertion parsing.
Every oauth, oidc & saml sso security testing we run is manual and evidence-led — automated scanning alone never tells you which weaknesses actually matter. We map your real environment, not a generic template, then test every path where trust is granted and every place where controls could be bypassed.
The result is clarity: a prioritised, exploitable-risk view of your oauth, oidc & saml sso attack surface that your team can act on immediately, backed by proof rather than a scanner's guesswork.
A convincing security posture is now a commercial requirement across the Cyprus market. A weakness that reaches customer or financial data can trigger a GDPR and NIS2 obligation, damage hard-won client trust, and stall deals while security questionnaires go unanswered. Our oauth, oidc & saml sso security testing exists to remove that uncertainty before an attacker — or an auditor — finds the gap first.
By proving exactly what is exploitable and what it would cost, we turn a vague worry into a concrete, fundable remediation plan. Cyprus firms use our reports to close real gaps, satisfy CySEC, GDPR and NIS2 expectations, and demonstrate genuine due diligence to clients, partners and insurers — with a free retest to prove the fixes hold.

How we run your engagement
Kick-off & scoping. A short call to agree goals, in-scope assets and rules of engagement, so your oauth, oidc & saml sso security testing is safe, authorised and aimed at your real business risk.
Mapping & discovery. Before touching anything we map the full attack surface in scope, so nothing exploitable slips through.
Hands-on testing. Cyprus-based specialists exploit and chain weaknesses manually — the flaws scanners walk straight past — to show genuine impact.
Reporting. Each issue is verified, CVSS-rated and documented with a step-by-step reproduction and a practical fix your team can apply.
Free retest. Once you have remediated, we re-test at no extra cost to confirm the attack path is truly closed.
Tools & techniques
We tailor each oauth, oidc & saml sso security testing to your stack, prioritising redirect_uri & state parameter abuse, authorization code & pkce flaws and jwt/id_token validation weaknesses and any control that stands between an attacker and your data.
Identity is the modern perimeter, so we test it as attackers do. For directory work we combine BloodHound attack-path analysis with manual abuse of Kerberos, delegation and trust relationships; for federation we walk every OAuth, OIDC and SAML flow by hand, hunting token, scope and assertion weaknesses. We prove privilege escalation and lateral movement rather than merely listing misconfigurations.
Because a single identity flaw can undermine every application behind it, we prioritise findings by how far they let an attacker move — from a low-privileged foothold to domain or tenant compromise — and give your team the exact remediation order.
When you need this engagement
You are deploying, changing or relying on systems where redirect_uri & state parameter abuse would be business-critical
You have deployed single sign-on across multiple business applications
You have suffered credential phishing or want to test its blast radius
You are consolidating identity during a merger or cloud migration
A regulator or client requires assurance over authentication and privileged access
What you receive
SSO flow security findings
Account-takeover PoCs where present
Implementation hardening guidance
Free retest after remediation
Your deliverables
When your oauth, oidc & saml sso security testing wraps up, you receive a clear, audit-ready report plus a walkthrough call with your team. Inside you will find:
A concise executive summary that management and the board can act on
Every technical finding with a reproducible, copy-paste proof of concept
CVSS v3.1 ratings and plain-language business impact for each issue
Practical, prioritised remediation your developers can implement straight away
A free retest and updated finding status once fixes are in place
A signed attestation letter for clients, auditors, GDPR, NIS2 and ISO 27001
By the end of your oauth, oidc & saml sso security testing, you will know exactly which weaknesses a real attacker could exploit, what it would cost your business, and the precise order in which to fix them — backed by evidence, not a scanner’s guesswork. Cyprus firms use our findings to close critical gaps, satisfy client and regulator security questionnaires, and demonstrate due diligence for GDPR and NIS2. With a free retest included, you also get documented proof the issues are resolved.
Working with us
Every oauth, oidc & saml sso security testing begins with a short, no-obligation scoping call to understand your goals, environment and constraints, followed by a fixed-price proposal. Most work is delivered remotely, and because we are based in Cyprus we work in your timezone with on-site visits across Limassol, Nicosia and island-wide where it helps. We keep you updated throughout and flag any critical finding immediately rather than waiting for the report. Everything is covered by a signed NDA and safe, non-disruptive testing that protects your production systems. You receive your report, a walkthrough and a complimentary retest once fixes land. Engagements are typically booked one to three weeks ahead, and urgent testing can often be arranged — just email hi@cypruspentest.com.
