Epieos Alternative for Investigations: DefenceCore vs Epieos
Quick answer
Epieos is a lookup. DefenceCore is an investigation. Epieos answers one question extremely well: which platforms is this email or phone number registered on? You get a list of accounts — Google metadata, Holehe results across 100+ sites — and then the investigation is yours to run. DefenceCore starts where Epieos stops: give it the email (or phone, username, IP, or wallet) and an agent pivots across open sources the way an analyst would, resolves an identity graph with a confidence score on every link, fires deterministic risk signals, and returns a sourced report with a recommended action.
Choose Epieos if you are an investigator who wants a fast, cheap registration-check as raw material for your own process. Choose DefenceCore if you need the finished case — connected, scored, cited, and ready to act on — in minutes, not hours.
What each tool is
Epieos (epieos.com) is one of the best-known reverse email and phone lookup tools in the OSINT community. Enter an email address and it enumerates where that address is registered — Google (name, profile photo, last-active metadata when exposed), Skype, LinkedIn, and 140+ sites and social networks via its Holehe integration — without notifying the target. It has a free tier for basic modules and paid plans for volume and full module access (public listings show roughly €19/month for 100 lookups and €49/month for 500 with API access; figures may change). It is a beloved, sharp, single-purpose instrument.
DefenceCore (defencecore.com) is an autonomous investigation platform for fraud, trust & safety, and compliance teams. You drop in the signals from a case — email, phone, username, IP, or crypto wallet — and the agent runs the pivots a trained investigator would: a breach record surfaces an alternate email, that email reveals a reused username, the username leads to linked accounts. The output is not a list of registrations; it is a resolved identity graph with linkage confidence on every connection, deterministic risk signals, and a single recommended action, with every claim cited to its source. See a sample report.
The real comparison is raw material versus finished work.
Side-by-side comparison
| Dimension | DefenceCore | Epieos |
|---|---|---|
| What it is | Autonomous investigation agent | Reverse email / phone lookup |
| Input | Email, phone, username, IP, or wallet — one or several | Email or phone number |
| What you get back | Resolved identity graph, risk signals, recommended action, sourced report | List of platforms where the identifier is registered, plus exposed metadata |
| Pivoting | Agent follows each finding to the next check automatically | Manual — you take each result and run the next lookup yourself |
| Evidence | Every claim cited; linkage confidence on every connection | Registration results shown; corroboration is your job |
| Risk assessment | Deterministic, versioned risk signals | None — interpretation is up to the analyst |
| Pricing | From $49/month (Starter, 25 investigations) to $199/month (Pro, 150 with deep scans) | Free tier; paid plans by lookup volume (≈€19–49/month, public listings) |
| Best for | Teams that need defensible cases at queue speed | Analysts who want fast registration-checks inside their own process |

Where DefenceCore is the better fit
1. You need the case, not the clue. An Epieos result is the start of an investigation: a list of platforms that becomes an hour of manual pivoting — breach checks, username searches, cross-referencing — before you can write anything defensible. DefenceCore runs those pivots itself and returns the written case: graph, signals, recommendation, sources. For a fraud queue that never empties, that difference decides which cases get investigated at all.
2. Your case rarely starts with just an email. Epieos takes an email or a phone. Real cases arrive as bundles — an email and a device IP and a crypto wallet from the same suspicious signup. DefenceCore accepts the bundle and resolves it into one identity picture, including on-chain wallet analysis that a registration-lookup tool has no equivalent for.
3. You have to defend the conclusion. A list of registrations doesn't say how strongly a discovered account belongs to your subject. DefenceCore scores every link — computed from corroboration count and source reliability, not model intuition — so a reviewer, an auditor, or a regulator can see what is certain versus circumstantial.
4. The people running cases aren't OSINT specialists. Epieos rewards analysts who already know what to do with its output. DefenceCore is built so a fraud-ops or T&S reviewer without OSINT training gets an expert-shaped investigation anyway.
Where Epieos is the better fit
1. You want the cheapest possible registration-check. If the only question is "where is this email registered?", Epieos answers it quickly and inexpensively, with a genuinely useful free tier.
2. You are the investigation engine. Experienced OSINT practitioners who run their own methodology often want sharp single-purpose instruments, not an agent. Epieos is exactly that instrument, and it composes well with other tools (including as a Maltego transform).
3. You need Google account metadata specifically. Epieos's Google module — name, photo, last-active when exposed — is a distinctive capability investigators reach for directly.
Using both
Plenty of professional workflows have room for both: Epieos as the quick, cheap check when a single registration answer is all you need, DefenceCore when the identifier is attached to a case — a chargeback, an abuse report, a KYC escalation — and what you actually need to produce is a documented, sourced investigation.
Frequently asked questions
Is DefenceCore an alternative to Epieos? For investigation work, yes — but they sit at different altitudes. Epieos returns raw material: the platforms where an email or phone is registered. DefenceCore returns the finished investigation: an identity graph with confidence-scored links, deterministic risk signals, and a recommended action, with every claim cited. If your output is a case file rather than a lookup result, DefenceCore is the alternative.
Does DefenceCore have a free tier like Epieos? DefenceCore is a paid product — from $49/month for 25 investigations (Starter) to $199/month for 150 investigations with deep scans (Pro) — so you get a full sourced investigation rather than a lookup result. Epieos's free tier covers basic lookup modules, with paid plans for volume and full access.
Can DefenceCore check which sites an email is registered on? Yes — account enumeration across platforms is one of the checks the agent runs, and the results land as nodes in the identity graph rather than as a standalone list. The difference is that DefenceCore then keeps going: breach exposure, reused usernames, linked identifiers, and risk signals, resolved into one picture.
Which is better for a fraud or trust & safety team? DefenceCore, in most cases. Epieos is built for the individual analyst mid-process; DefenceCore is built for a queue — every flagged signup or reported account gets a sourced, reviewable case in minutes, without requiring OSINT expertise from the reviewer.
Does either tool notify the person being investigated? No. Both work from open and commercially available sources without alerting the subject. DefenceCore additionally intent-screens signups and is built for verified security and investigation teams — it is not a people-search service, and reports may not be used for credit, employment, housing, or insurance decisions.

The cleanest way to compare a lookup with an investigation is to look at what lands on your desk afterward. View a sample DefenceCore report — a resolved identity graph, defined risk signals, and a recommended action — then run one on a case of your own.
