RowShield vs Burp Suite: manual testing vs continuous RLS checks
The short version
- Burp Suite is the professional toolkit for hands-on web application testing: an intercepting proxy with Repeater, Intruder, an embedded scanner in paid editions and an extension marketplace. RowShield is a continuous verifier for the layer beneath the HTTP: it evaluates Supabase policies and catalog state directly, automatically, on every change.
- Choose Burp Suite when — you employ skilled application security practitioners who need best-in-class tooling for manual exploration and adversarial testing across many technologies.
- Choose RowShield when — you are a product team shipping Supabase changes weekly and need RLS posture, service-key exposure and drift checked automatically at pull-request time, without booking practitioner hours.

Head to head: Burp Suite vs RowShield
| Capability | Burp Suite | RowShield | Edge |
|---|---|---|---|
| Operating model | Human-driven analysis through an intercepting proxy and scanner, session by session. | Automated continuous verification triggered by migrations and configuration changes. | RowShield |
| Layer of visibility | HTTP traffic: requests, responses, parameters and cookies. | Database catalog, policies, grants, roles and generated API semantics. | RowShield |
| RLS semantics | Inferable only if an operator crafts targeted requests and reads responses carefully. | Policy definitions evaluated directly; permissive or absent protection detected as such. | RowShield |
| Filtered versus empty results | Both look like ordinary 200 responses unless manually investigated. | Separates policy-filtered emptiness from genuinely empty tables automatically. | RowShield |
| Coverage decay | Findings describe the application as it existed during the test. | No decay: each subsequent migration is re-checked on arrival. | RowShield |
| Skill requirement | Requires trained application security practitioners to be effective. | Designed for product engineers; findings read like review tickets. | RowShield |
| Manual testing depth | Best-in-class tooling for exploitation, fuzzing and extension workflows. | Not the goal; RowShield automates a narrow, well-defined check set. | Burp Suite |

What Burp Suite does
Burp Suite, published by PortSwigger Ltd., is a platform for web application security testing built around an intercepting proxy, and in experienced hands it is extraordinarily flexible. Practitioners capture and replay requests in Repeater, automate customised attacks with Intruder, enumerate surfaces with the crawler, and run the embedded scanner in the Professional and Enterprise editions.
An extension marketplace adds protocol handlers, session handling logic and custom checks. This depth explains why the suite appears in nearly every professional web application engagement, and why PortSwigger also runs widely respected training material alongside it. Nothing in this page should be read as criticism of that craft.
Where the scopes differ
Burp works on evidence visible in HTTP. Supabase authorisation is enforced before HTTP is even produced: policies decide which rows exist for a caller, and PostgREST renders the outcome. A filtered result and an empty table render identically, so even a careful operator must consult schema knowledge outside the tool to interpret what they see.
Whether protection on a table was silently dropped, a grant widened, or a privileged function added is invisible in a response body. Burp will happily test whatever endpoints it is pointed at; it simply has no representation of the policy layer those endpoints express, so conclusions about authorisation remain indirect and laborious.
There is also the matter of after. An engagement ends; migrations continue. Whatever was verified during the session describes a system that the next dozen merges may quietly alter.
Why Supabase teams choose RowShield over Burp Suite
Choosing RowShield is not a judgement about Burp quality; it is a decision about who verifies what, how often. Product engineers shipping Supabase applications need to know that a migration did not disable protection, widen anon access or leak a service-role key, and they need to know at pull-request time.
RowShield delivers exactly that: named rules including RLS_DISABLED, ANON_TABLE_READABLE and SERVICE_ROLE_KEY_EXPOSED, evaluated against live catalog state, with drift surfaced against the previous known posture. No scheduling of practitioner time, no interpreting scanner output, no waiting for the next engagement.
Specificity, latency-to-alert and cost all favour a purpose-built tool for this narrow, critical job: minutes from commit to named diagnosis, at a subscription price rather than a consultancy rate.
Where Burp Suite is the right choice
If your team includes application security professionals performing adversarial testing across many technologies, Burp remains an outstanding investment and we recommend it without reservation for that purpose. Complex custom endpoints, business-logic flaws and chained exploits require human creativity that no continuous monitor provides.
The pivot is coverage economics: human attention is scarce and expensive, and spending it re-verifying that row level security is still enabled on core tables wastes it. Automate the deterministic posture checks with RowShield and reserve skilled operators, in-house or contracted, for the work only they can do.
Using both
The combination is stronger than either alone. RowShield maintains a continuously verified baseline of your Supabase authorisation posture, so anyone arriving with Burp starts from an environment already known to be sound and spends engagement time on business logic instead of configuration hygiene.
After the engagement lands its report, subsequent migrations are watched automatically, so the decay window between findings and present reality closes. Teams adopting this pattern treat Burp sessions as deep audits punctuating a continuously monitored system rather than the only line of defence.
Frequently asked
- Is RowShield affiliated with PortSwigger Ltd.?
- No. RowShield is developed by Veristria and has no affiliation with, endorsement from or sponsorship by PortSwigger Ltd. Burp Suite is a trademark of PortSwigger Ltd., and references on this page are purely comparative.
- Is RowShield a good Burp Suite alternative?
- For the Supabase authorisation layer, yes: RowShield covers deterministically what episodic manual testing has never sustained between engagements. For broad adversarial testing across arbitrary web technologies, keep Burp and the professionals who drive it; the two answer different questions.
- Can Burp Suite test row level security on a Supabase backend?
- Manually, yes: an operator can craft requests as different roles and compare responses, which is slow and requires deep context. What Burp cannot do is read policy definitions directly, distinguish filtered from empty results automatically, or alert when the next migration changes behaviour. RowShield performs those checks continuously and names the affected objects.
