## Proof&Trust

Proof&Trust targets the supply-chain obligation created by NIS2 Article 21(2)(d), which makes the security posture of direct suppliers the responsibility of the buying organisation. Instead of chasing annual questionnaires across document stores, the platform ingests contracts, vendor masters and document repositories, then automatically validates the authenticity, validity and scope of certificates, attestations, SBOMs, penetration-test reports and policies.

Each artifact receives an evidence-grade score based on completeness, recency, source trust and control coverage. These scores roll up into a vendor risk index that is recalculated continuously rather than frozen at an annual snapshot, and vendors are auto-classified into tiers — critical/high, important/medium and baseline/low — according to dependency, concentration and evidence quality. Tier changes are timestamped, traceable to the underlying evidence, and exportable as audit-ready proof, so a new CVE or expired certificate can move a vendor up the risk ladder within minutes.

The vendor says a sample portfolio can be scored in under 30 minutes with no integration and no credit card, in an EU-hosted environment with data residency and encryption in transit and at rest. Reporting is mapped across all ten NIS2 Article 21(2) measures, and the platform also supports Article 23 incident-notification drafting with 24-hour early-warning timing. The offering is aimed at compliance, security and procurement teams in regulated sectors such as banking, energy, healthcare, telecom and the public sector.

**Pricing & Plans:** Published annual tiers in euros (excluding VAT). Basic: €1,999/year for up to 20 vendor assessments. Professional: €4,900/year for up to 100. Enterprise: €9,900+/year for up to 300, with custom branding, a read-only auditor account, API export and SLA. Larger portfolios and private/on-prem deployments are quoted individually. A free sample assessment and a free trial are offered.

- **Evidence ingestion and validation:** Connects contracts, vendor masters and document stores, then verifies the authenticity, validity and scope of certificates, attestations, SBOMs, pen-test reports and policies.
- **Artifact and vendor scoring:** Scores each artifact on completeness, recency, source trust and control coverage, then rolls the results into a continuously recalculated vendor risk index.
- **Continuous NIS2 tiering:** Auto-classifies vendors into critical, important and baseline tiers by dependency, concentration and evidence quality, re-tiering the moment evidence changes.
- **Audit-ready reporting:** Produces cited, exportable evidence trails mapped to all ten NIS2 Article 21(2) measures, plus Article 23 incident-notification drafting with 24-hour early-warning timing.
- **No-integration onboarding:** Drop in a sample of supplier evidence and receive a scored, tiered portfolio in under 30 minutes, with NDA available and EU-hosted data residency.

**Strengths:** Published euro pricing makes budgeting straightforward, unlike many compliance platforms; Continuous scoring and re-tiering beats an annual questionnaire snapshot when risk changes mid-year; No integration is required to get a first scored portfolio, and a free sample assessment lowers the trial risk; EU-hosted with data residency and explicit mapping to all ten NIS2 Article 21(2) measures

**Limitations:** Focused squarely on NIS2, so organisations outside its scope get less out of the tiering model; Assessment caps per tier (20/100/300) mean very large vendor estates need a custom quote; It is a newer platform, so it lacks the long public track record of established GRC suites

## ZeroGPT

ZeroGPT is best known as an AI content detector, but the site has expanded into a full writing and verification toolkit. The core AI/GPT detector lets you paste text or upload a file and returns a highlighted analysis showing which sentences look machine-written, with a percentage gauge and an automatically generated PDF report you can use as documentation.

Around that core sit several companion detectors and writers. The AI image detector and AI video detector extend checking beyond text; the plagiarism checker scans against billions of sources; and the AI humanizer and paraphraser rewrite text into a more natural style. A grammar checker, summarizer, translator, dictionary, word counter, citation generator, and AI email helper round out day-to-day writing tasks. The company says its multi-stage DeepAnalyse model is trained on internet text, educational datasets, and proprietary synthetic AI datasets, covers over 35 LLM families, and reports 98.4% detection accuracy with a false positive rate under 1%.

Access is freemium: the main tools work free in the browser, with MAX and EXPERT subscriptions for heavier use and premium features, and a separate API for organizations that need large-scale integration. ZeroGPT also runs on WhatsApp and Telegram through a bot, letting you chat, detect AI text, summarize, paraphrase, translate, and check grammar without leaving the messaging app.

**Pricing & Plans:** Freemium with paid tiers. Core tools such as the AI detector, summarizer, and grammar checker are usable free in the browser, while MAX and EXPERT subscriptions unlock higher limits and premium features, and API access is sold separately for organizations.

- **AI and ChatGPT detection:** Paste up to 15,000 characters or upload a file and get a highlighted breakdown of which sentences appear AI-written, plus an overall percentage score and a downloadable PDF report.
- **AI image and video detection:** Beyond text, ZeroGPT offers an AI image detector and an AI video detector that performs frame-level analysis to flag generated or manipulated visuals.
- **Plagiarism checking and humanizing:** Compare your text against billions of sources through the plagiarism checker, or rewrite and humanize AI text with the paraphraser and AI humanizer while keeping the original meaning.
- **Writing and productivity tools:** A bundled writing suite covers summarization, grammar and spelling correction, translation across many languages, a dictionary, word and character counting, citation generation, and an AI email writer.
- **API for organizations:** A documented REST API exposes detection, plagiarism, paraphrasing, summarization, grammar, chatbot, and translation endpoints for organizations that need to embed ZeroGPT at scale.

**Strengths:** Free browser access to the core AI detector, summarizer, and grammar checker; Sentence-level highlighting with an overall percentage and exportable PDF reports; Extends beyond text to AI image and video detection, plus plagiarism checking; Broad companion toolkit: humanizer, paraphraser, translator, dictionary, citations, email helper

**Limitations:** AI detectors can produce false positives, so results should be treated as a signal rather than proof; The strongest features sit behind MAX/EXPERT paid tiers and API access is a separate purchase; Character limits apply to the free detection box; No detection tool can guarantee correctness across every model and language
